Struct std::os::unix::io::OwnedFd

source · [−]

#[repr(transparent)]
pub struct OwnedFd { /* private fields */ }

🔬 This is a nightly-only experimental API. (io_safety #87074)

This is supported on Unix only.

Expand description

An owned file descriptor.

This closes the file descriptor on drop.

This uses repr(transparent) and has the representation of a host file descriptor, so it can be used in FFI in places where a file descriptor is passed as a consumed argument or returned as an owned value, and it never has the value -1.

Implementations

source

impl OwnedFd

source

pub fn try_clone(&self) -> Result<Self>

🔬 This is a nightly-only experimental API. (io_safety #87074)

Creates a new OwnedFd instance that shares the same underlying file handle as the existing OwnedFd instance.
