Function std::fs::try_exists

pub fn try_exists<P: AsRef<Path>>(path: P) -> Result<bool>

🔬 This is a nightly-only experimental API. (path_try_exists #83186)

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.)

Examples

#![feature(path_try_exists)]
use std::fs;

assert!(!fs::try_exists("does_not_exist.txt").expect("Can't check existence of file does_not_exist.txt"));
assert!(fs::try_exists("/root/secret_file.txt").is_err());
