Struct std::path::PathBuf

1.0.0 · source · [−]
pub struct PathBuf { /* private fields */ }
Expand description

An owned, mutable path (akin to String).

This type provides methods like push and set_extension that mutate the path in place. It also implements Deref to Path, meaning that all methods on Path slices are available on PathBuf values as well.

More details about the overall approach can be found in the module documentation.

Examples

You can use push to build up a PathBuf from components:

use std::path::PathBuf;

let mut path = PathBuf::new();

path.push(r"C:\");
path.push("windows");
path.push("system32");

path.set_extension("dll");
Run

However, push is best used for dynamic situations. This is a better way to do this when you know all of the components ahead of time:

use std::path::PathBuf;

let path: PathBuf = [r"C:\", "windows", "system32.dll"].iter().collect();
Run

We can still do better than this! Since these are all strings, we can use From::from:

use std::path::PathBuf;

let path = PathBuf::from(r"C:\windows\system32.dll");
Run

Which method works best depends on what kind of situation you’re in.

Implementations

Allocates an empty PathBuf.

Examples
use std::path::PathBuf;

let path = PathBuf::new();
Run

Creates a new PathBuf with a given capacity used to create the internal OsString. See with_capacity defined on OsString.

Examples
use std::path::PathBuf;

let mut path = PathBuf::with_capacity(10);
let capacity = path.capacity();

// This push is done without reallocating
path.push(r"C:\");

assert_eq!(capacity, path.capacity());
Run

Coerces to a Path slice.

Examples
use std::path::{Path, PathBuf};

let p = PathBuf::from("/test");
assert_eq!(Path::new("/test"), p.as_path());
Run

Extends self with path.

If path is absolute, it replaces the current path.

On Windows:

  • if path has a root but no prefix (e.g., \windows), it replaces everything except for the prefix (if any) of self.
  • if path has a prefix but no root, it replaces self.
  • if self has a verbatim prefix (e.g. \\?\C:\windows) and path is not empty, the new path is normalized: all references to . and .. are removed.
Examples

Pushing a relative path extends the existing path:

use std::path::PathBuf;

let mut path = PathBuf::from("/tmp");
path.push("file.bk");
assert_eq!(path, PathBuf::from("/tmp/file.bk"));
Run

Pushing an absolute path replaces the existing path:

use std::path::PathBuf;

let mut path = PathBuf::from("/tmp");
path.push("/etc");
assert_eq!(path, PathBuf::from("/etc"));
Run

Truncates self to self.parent.

Returns false and does nothing if self.parent is None. Otherwise, returns true.

Examples
use std::path::{Path, PathBuf};

let mut p = PathBuf::from("/spirited/away.rs");

p.pop();
assert_eq!(Path::new("/spirited"), p);
p.pop();
assert_eq!(Path::new("/"), p);
Run

Updates self.file_name to file_name.

If self.file_name was None, this is equivalent to pushing file_name.

Otherwise it is equivalent to calling pop and then pushing file_name. The new path will be a sibling of the original path. (That is, it will have the same parent.)

Examples
use std::path::PathBuf;

let mut buf = PathBuf::from("/");
assert!(buf.file_name() == None);
buf.set_file_name("bar");
assert!(buf == PathBuf::from("/bar"));
assert!(buf.file_name().is_some());
buf.set_file_name("baz.txt");
assert!(buf == PathBuf::from("/baz.txt"));
Run

Updates self.extension to extension.

Returns false and does nothing if self.file_name is None, returns true and updates the extension otherwise.

If self.extension is None, the extension is added; otherwise it is replaced.

Examples
use std::path::{Path, PathBuf};

let mut p = PathBuf::from("/feel/the");

p.set_extension("force");
assert_eq!(Path::new("/feel/the.force"), p.as_path());

p.set_extension("dark_side");
assert_eq!(Path::new("/feel/the.dark_side"), p.as_path());
Run

Consumes the PathBuf, yielding its internal OsString storage.

Examples
use std::path::PathBuf;

let p = PathBuf::from("/the/head");
let os_str = p.into_os_string();
Run

Converts this PathBuf into a boxed Path.

Invokes capacity on the underlying instance of OsString.

Invokes clear on the underlying instance of OsString.

Invokes reserve on the underlying instance of OsString.

Invokes try_reserve on the underlying instance of OsString.

Invokes reserve_exact on the underlying instance of OsString.

Invokes try_reserve_exact on the underlying instance of OsString.

Invokes shrink_to_fit on the underlying instance of OsString.

Invokes shrink_to on the underlying instance of OsString.

Methods from Deref<Target = Path>

Yields the underlying OsStr slice.

Examples
use std::path::Path;

let os_str = Path::new("foo.txt").as_os_str();
assert_eq!(os_str, std::ffi::OsStr::new("foo.txt"));
Run

Yields a &str slice if the Path is valid unicode.

This conversion may entail doing a check for UTF-8 validity. Note that validation is performed because non-UTF-8 strings are perfectly valid for some OS.

Examples
use std::path::Path;

let path = Path::new("foo.txt");
assert_eq!(path.to_str(), Some("foo.txt"));
Run

Converts a Path to a Cow<str>.

Any non-Unicode sequences are replaced with U+FFFD REPLACEMENT CHARACTER.

Examples

Calling to_string_lossy on a Path with valid unicode:

use std::path::Path;

let path = Path::new("foo.txt");
assert_eq!(path.to_string_lossy(), "foo.txt");
Run

Had path contained invalid unicode, the to_string_lossy call might have returned "fo�.txt".

Converts a Path to an owned PathBuf.

Examples
use std::path::Path;

let path_buf = Path::new("foo.txt").to_path_buf();
assert_eq!(path_buf, std::path::PathBuf::from("foo.txt"));
Run

Returns true if the Path is absolute, i.e., if it is independent of the current directory.

  • On Unix, a path is absolute if it starts with the root, so is_absolute and has_root are equivalent.

  • On Windows, a path is absolute if it has a prefix and starts with the root: c:\windows is absolute, while c:temp and \temp are not.

Examples
use std::path::Path;

assert!(!Path::new("foo.txt").is_absolute());
Run

Returns true if the Path is relative, i.e., not absolute.

See is_absolute’s documentation for more details.

Examples
use std::path::Path;

assert!(Path::new("foo.txt").is_relative());
Run

Returns true if the Path has a root.

  • On Unix, a path has a root if it begins with /.

  • On Windows, a path has a root if it:

    • has no prefix and begins with a separator, e.g., \windows
    • has a prefix followed by a separator, e.g., c:\windows but not c:windows
    • has any non-disk prefix, e.g., \\server\share
Examples
use std::path::Path;

assert!(Path::new("/etc/passwd").has_root());
Run

Returns the Path without its final component, if there is one.

Returns None if the path terminates in a root or prefix.

Examples
use std::path::Path;

let path = Path::new("/foo/bar");
let parent = path.parent().unwrap();
assert_eq!(parent, Path::new("/foo"));

let grand_parent = parent.parent().unwrap();
assert_eq!(grand_parent, Path::new("/"));
assert_eq!(grand_parent.parent(), None);
Run

Produces an iterator over Path and its ancestors.

The iterator will yield the Path that is returned if the parent method is used zero or more times. That means, the iterator will yield &self, &self.parent().unwrap(), &self.parent().unwrap().parent().unwrap() and so on. If the parent method returns None, the iterator will do likewise. The iterator will always yield at least one value, namely &self.

Examples
use std::path::Path;

let mut ancestors = Path::new("/foo/bar").ancestors();
assert_eq!(ancestors.next(), Some(Path::new("/foo/bar")));
assert_eq!(ancestors.next(), Some(Path::new("/foo")));
assert_eq!(ancestors.next(), Some(Path::new("/")));
assert_eq!(ancestors.next(), None);

let mut ancestors = Path::new("../foo/bar").ancestors();
assert_eq!(ancestors.next(), Some(Path::new("../foo/bar")));
assert_eq!(ancestors.next(), Some(Path::new("../foo")));
assert_eq!(ancestors.next(), Some(Path::new("..")));
assert_eq!(ancestors.next(), Some(Path::new("")));
assert_eq!(ancestors.next(), None);
Run

Returns the final component of the Path, if there is one.

If the path is a normal file, this is the file name. If it’s the path of a directory, this is the directory name.

Returns None if the path terminates in ...

Examples
use std::path::Path;
use std::ffi::OsStr;

assert_eq!(Some(OsStr::new("bin")), Path::new("/usr/bin/").file_name());
assert_eq!(Some(OsStr::new("foo.txt")), Path::new("tmp/foo.txt").file_name());
assert_eq!(Some(OsStr::new("foo.txt")), Path::new("foo.txt/.").file_name());
assert_eq!(Some(OsStr::new("foo.txt")), Path::new("foo.txt/.//").file_name());
assert_eq!(None, Path::new("foo.txt/..").file_name());
assert_eq!(None, Path::new("/").file_name());
Run

Returns a path that, when joined onto base, yields self.

Errors

If base is not a prefix of self (i.e., starts_with returns false), returns Err.

Examples
use std::path::{Path, PathBuf};

let path = Path::new("/test/haha/foo.txt");

assert_eq!(path.strip_prefix("/"), Ok(Path::new("test/haha/foo.txt")));
assert_eq!(path.strip_prefix("/test"), Ok(Path::new("haha/foo.txt")));
assert_eq!(path.strip_prefix("/test/"), Ok(Path::new("haha/foo.txt")));
assert_eq!(path.strip_prefix("/test/haha/foo.txt"), Ok(Path::new("")));
assert_eq!(path.strip_prefix("/test/haha/foo.txt/"), Ok(Path::new("")));

assert!(path.strip_prefix("test").is_err());
assert!(path.strip_prefix("/haha").is_err());

let prefix = PathBuf::from("/test/");
assert_eq!(path.strip_prefix(prefix), Ok(Path::new("haha/foo.txt")));
Run

Determines whether base is a prefix of self.

Only considers whole path components to match.

Examples
use std::path::Path;

let path = Path::new("/etc/passwd");

assert!(path.starts_with("/etc"));
assert!(path.starts_with("/etc/"));
assert!(path.starts_with("/etc/passwd"));
assert!(path.starts_with("/etc/passwd/")); // extra slash is okay
assert!(path.starts_with("/etc/passwd///")); // multiple extra slashes are okay

assert!(!path.starts_with("/e"));
assert!(!path.starts_with("/etc/passwd.txt"));

assert!(!Path::new("/etc/foo.rs").starts_with("/etc/foo"));
Run

Determines whether child is a suffix of self.

Only considers whole path components to match.

Examples
use std::path::Path;

let path = Path::new("/etc/resolv.conf");

assert!(path.ends_with("resolv.conf"));
assert!(path.ends_with("etc/resolv.conf"));
assert!(path.ends_with("/etc/resolv.conf"));

assert!(!path.ends_with("/resolv.conf"));
assert!(!path.ends_with("conf")); // use .extension() instead
Run

Extracts the stem (non-extension) portion of self.file_name.

The stem is:

  • None, if there is no file name;
  • The entire file name if there is no embedded .;
  • The entire file name if the file name begins with . and has no other .s within;
  • Otherwise, the portion of the file name before the final .
Examples
use std::path::Path;

assert_eq!("foo", Path::new("foo.rs").file_stem().unwrap());
assert_eq!("foo.tar", Path::new("foo.tar.gz").file_stem().unwrap());
Run
See Also

This method is similar to Path::file_prefix, which extracts the portion of the file name before the first .

🔬This is a nightly-only experimental API. (path_file_prefix #86319)

Extracts the prefix of self.file_name.

The prefix is:

  • None, if there is no file name;
  • The entire file name if there is no embedded .;
  • The portion of the file name before the first non-beginning .;
  • The entire file name if the file name begins with . and has no other .s within;
  • The portion of the file name before the second . if the file name begins with .
Examples
use std::path::Path;

assert_eq!("foo", Path::new("foo.rs").file_prefix().unwrap());
assert_eq!("foo", Path::new("foo.tar.gz").file_prefix().unwrap());
Run
See Also

This method is similar to Path::file_stem, which extracts the portion of the file name before the last .

Extracts the extension of self.file_name, if possible.

The extension is:

  • None, if there is no file name;
  • None, if there is no embedded .;
  • None, if the file name begins with . and has no other .s within;
  • Otherwise, the portion of the file name after the final .
Examples
use std::path::Path;

assert_eq!("rs", Path::new("foo.rs").extension().unwrap());
assert_eq!("gz", Path::new("foo.tar.gz").extension().unwrap());
Run

Creates an owned PathBuf with path adjoined to self.

See PathBuf::push for more details on what it means to adjoin a path.

Examples
use std::path::{Path, PathBuf};

assert_eq!(Path::new("/etc").join("passwd"), PathBuf::from("/etc/passwd"));
Run

Creates an owned PathBuf like self but with the given file name.

See PathBuf::set_file_name for more details.

Examples
use std::path::{Path, PathBuf};

let path = Path::new("/tmp/foo.txt");
assert_eq!(path.with_file_name("bar.txt"), PathBuf::from("/tmp/bar.txt"));

let path = Path::new("/tmp");
assert_eq!(path.with_file_name("var"), PathBuf::from("/var"));
Run

Creates an owned PathBuf like self but with the given extension.

See PathBuf::set_extension for more details.

Examples
use std::path::{Path, PathBuf};

let path = Path::new("foo.rs");
assert_eq!(path.with_extension("txt"), PathBuf::from("foo.txt"));

let path = Path::new("foo.tar.gz");
assert_eq!(path.with_extension(""), PathBuf::from("foo.tar"));
assert_eq!(path.with_extension("xz"), PathBuf::from("foo.tar.xz"));
assert_eq!(path.with_extension("").with_extension("txt"), PathBuf::from("foo.txt"));
Run

Produces an iterator over the Components of the path.

When parsing the path, there is a small amount of normalization:

  • Repeated separators are ignored, so a/b and a//b both have a and b as components.

  • Occurrences of . are normalized away, except if they are at the beginning of the path. For example, a/./b, a/b/, a/b/. and a/b all have a and b as components, but ./a/b starts with an additional CurDir component.

  • A trailing slash is normalized away, /a/b and /a/b/ are equivalent.

Note that no other normalization takes place; in particular, a/c and a/b/../c are distinct, to account for the possibility that b is a symbolic link (so its parent isn’t a).

Examples
use std::path::{Path, Component};
use std::ffi::OsStr;

let mut components = Path::new("/tmp/foo.txt").components();

assert_eq!(components.next(), Some(Component::RootDir));
assert_eq!(components.next(), Some(Component::Normal(OsStr::new("tmp"))));
assert_eq!(components.next(), Some(Component::Normal(OsStr::new("foo.txt"))));
assert_eq!(components.next(), None)
Run

Produces an iterator over the path’s components viewed as OsStr slices.

For more information about the particulars of how the path is separated into components, see components.

Examples
use std::path::{self, Path};
use std::ffi::OsStr;

let mut it = Path::new("/tmp/foo.txt").iter();
assert_eq!(it.next(), Some(OsStr::new(&path::MAIN_SEPARATOR.to_string())));
assert_eq!(it.next(), Some(OsStr::new("tmp")));
assert_eq!(it.next(), Some(OsStr::new("foo.txt")));
assert_eq!(it.next(), None)
Run

Returns an object that implements Display for safely printing paths that may contain non-Unicode data. This may perform lossy conversion, depending on the platform. If you would like an implementation which escapes the path please use Debug instead.

Examples
use std::path::Path;

let path = Path::new("/tmp/foo.rs");

println!("{}", path.display());
Run

Queries the file system to get information about a file, directory, etc.

This function will traverse symbolic links to query information about the destination file.

This is an alias to fs::metadata.

Examples
use std::path::Path;

let path = Path::new("/Minas/tirith");
let metadata = path.metadata().expect("metadata call failed");
println!("{:?}", metadata.file_type());
Run

Queries the metadata about a file without following symlinks.

This is an alias to fs::symlink_metadata.

Examples
use std::path::Path;

let path = Path::new("/Minas/tirith");
let metadata = path.symlink_metadata().expect("symlink_metadata call failed");
println!("{:?}", metadata.file_type());
Run

Returns the canonical, absolute form of the path with all intermediate components normalized and symbolic links resolved.

This is an alias to fs::canonicalize.

Examples
use std::path::{Path, PathBuf};

let path = Path::new("/foo/test/../test/bar.rs");
assert_eq!(path.canonicalize().unwrap(), PathBuf::from("/foo/test/bar.rs"));
Run

Reads a symbolic link, returning the file that the link points to.

This is an alias to fs::read_link.

Examples
use std::path::Path;

let path = Path::new("/laputa/sky_castle.rs");
let path_link = path.read_link().expect("read_link call failed");
Run

Returns an iterator over the entries within a directory.

The iterator will yield instances of io::Result<fs::DirEntry>. New errors may be encountered after an iterator is initially constructed.

This is an alias to fs::read_dir.

Examples
use std::path::Path;

let path = Path::new("/laputa");
for entry in path.read_dir().expect("read_dir call failed") {
    if let Ok(entry) = entry {
        println!("{:?}", entry.path());
    }
}
Run

Returns true if the path points at an existing entity.

Warning: this method may be error-prone, consider using try_exists() instead! It also has a risk of introducing time-of-check to time-of-use (TOCTOU) bugs.

This function will traverse symbolic links to query information about the destination file.

If you cannot access the metadata of the file, e.g. because of a permission error or broken symbolic links, this will return false.

Examples
use std::path::Path;
assert!(!Path::new("does_not_exist.txt").exists());
Run
See Also

This is a convenience function that coerces errors to false. If you want to check errors, call Path::try_exists.

Returns Ok(true) if the path points at an existing entity.

This function will traverse symbolic links to query information about the destination file. In case of broken symbolic links this will return Ok(false).

As opposed to the exists() method, this one doesn’t silently ignore errors unrelated to the path not existing. (E.g. it will return Err(_) in case of permission denied on some of the parent directories.)

Note that while this avoids some pitfalls of the exists() method, it still can not prevent time-of-check to time-of-use (TOCTOU) bugs. You should only use it in scenarios where those bugs are not an issue.

Examples
use std::path::Path;
assert!(!Path::new("does_not_exist.txt").try_exists().expect("Can't check existence of file does_not_exist.txt"));
assert!(Path::new("/root/secret_file.txt").try_exists().is_err());
Run

Returns true if the path exists on disk and is pointing at a regular file.

This function will traverse symbolic links to query information about the destination file.

If you cannot access the metadata of the file, e.g. because of a permission error or broken symbolic links, this will return false.

Examples
use std::path::Path;
assert_eq!(Path::new("./is_a_directory/").is_file(), false);
assert_eq!(Path::new("a_file.txt").is_file(), true);
Run
See Also

This is a convenience function that coerces errors to false. If you want to check errors, call fs::metadata and handle its Result. Then call fs::Metadata::is_file if it was Ok.

When the goal is simply to read from (or write to) the source, the most reliable way to test the source can be read (or written to) is to open it. Only using is_file can break workflows like diff <( prog_a ) on a Unix-like system for example. See fs::File::open or fs::OpenOptions::open for more information.

Returns true if the path exists on disk and is pointing at a directory.

This function will traverse symbolic links to query information about the destination file.

If you cannot access the metadata of the file, e.g. because of a permission error or broken symbolic links, this will return false.

Examples
use std::path::Path;
assert_eq!(Path::new("./is_a_directory/").is_dir(), true);
assert_eq!(Path::new("a_file.txt").is_dir(), false);
Run
See Also

This is a convenience function that coerces errors to false. If you want to check errors, call fs::metadata and handle its Result. Then call fs::Metadata::is_dir if it was Ok.

Returns true if the path exists on disk and is pointing at a symbolic link.

This function will not traverse symbolic links. In case of a broken symbolic link this will also return true.

If you cannot access the directory containing the file, e.g., because of a permission error, this will return false.

Examples
use std::path::Path;
use std::os::unix::fs::symlink;

let link_path = Path::new("link");
symlink("/origin_does_not_exist/", link_path).unwrap();
assert_eq!(link_path.is_symlink(), true);
assert_eq!(link_path.exists(), false);
Run
See Also

This is a convenience function that coerces errors to false. If you want to check errors, call fs::symlink_metadata and handle its Result. Then call fs::Metadata::is_symlink if it was Ok.
