Struct OwnedFd

1.66.0 · Source 
pub struct OwnedFd { /* private fields */ }
Available on crate feature std only.
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.

You can use AsFd::as_fd to obtain a BorrowedFd.
