Struct FdRef 

pub struct FdRef { /* private fields */ }

A zero-cost (well, very, very, low cost) borrow of an OwnedFd.

This cannot be constructed directly, and can only exist as &FdRef.

As a result, it might be slightly larger than a bare RawFd.

Implementations

impl FdRef

pub unsafe fn from_unowned_raw<'a>(i: RawFd) -> &'a FdRef

Construct a FdRef reference from a RawFd. No ownership is taken.

unsafety:

• @i must be a valid fd
• the lifetime ’a must be appropriately bound

Trait Implementations

impl AsRawFd for FdRef

fn as_raw_fd(&self) -> RawFd

Extracts the raw file descriptor.

impl Borrow<FdRef> for OwnedFd

fn borrow(&self) -> &FdRef

Immutably borrows from an owned value.

impl ToOwned for FdRef

type Owned = OwnedFd

The resulting type after obtaining ownership.

fn to_owned(&self) -> Self::Owned

Creates owned data from borrowed data, usually by cloning.

fn clone_into(&self, target: &mut Self::Owned)

Uses borrowed data to replace owned data, usually by cloning.
