Struct uapi::OwnedFd

pub struct OwnedFd { /* private fields */ }

An owned file descriptor

Upon Drop, the contained file descriptor will be closed. Errors from close() are ignored.

The contained file descriptor can be accessed via deref: *self.

This struct can be converted From and Into various std types.

This struct implements AsFd, however, note that we do not enforce the requirements of BorrowedFd.

Implementations

impl OwnedFd

pub fn borrow(&self) -> Fd

Shortcut for Fd::new(*self)

pub fn unwrap(self) -> c_int

Returns *self and does not run Drop

pub fn raw(&self) -> c_int
