pub trait AsFd {
// Required method
fn as_fd(&self) -> BorrowedFd<'_>;
}
Expand description
A trait to borrow the file descriptor from an underlying object.
This is only available on unix platforms and must be imported in order to
call the method. Windows platforms have a corresponding AsHandle
and
AsSocket
set of traits.
Required Methods§
1.63.0 · Sourcefn as_fd(&self) -> BorrowedFd<'_>
fn as_fd(&self) -> BorrowedFd<'_>
