Struct rustix::fd::OwnedFd

1.63.0 · source ·
pub struct OwnedFd { /* private fields */ }
Expand description

An owned file descriptor.

This closes the file descriptor on drop. It is guaranteed that nobody else will close the file descriptor.

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.

impl FromRawFd for OwnedFd

source§

unsafe fn from_raw_fd(fd: i32) -> OwnedFd

Constructs a new instance of Self from the given raw file descriptor.

Safety

The resource pointed to by fd must be open and suitable for assuming ownership. The resource must not require any cleanup other than close.
