Struct SharedFd

pub struct SharedFd<T>(/* private fields */);

A shared fd. It is passed to the operations to make sure the fd won’t be closed before the operations complete.

Implementations

impl<T: AsFd> SharedFd<T>

pub fn new(fd: T) -> Self

Create the shared fd from an owned fd.

impl<T> SharedFd<T>

pub unsafe fn new_unchecked(fd: T) -> Self

Create the shared fd.

Safety

• T should own the fd.

pub fn try_unwrap(self) -> Result<T, Self>

Try to take the inner owned fd.

pub fn take(self) -> impl Future<Output = Option<T>>

Wait and take the inner owned fd.
