Struct io_lifetimes::OwnedFd

#[repr(transparent)]
pub struct OwnedFd { /* fields omitted */ }

An owned file descriptor.

This closes the file descriptor on drop.

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.

Trait Implementations

impl AsFd for OwnedFd

fn as_fd(&self) -> BorrowedFd<'_>

Borrows the file descriptor.

impl AsRawFd for OwnedFd

fn as_raw_fd(&self) -> RawFd

Extracts the raw file descriptor.

impl Debug for OwnedFd

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Drop for OwnedFd

fn drop(&mut self)

Executes the destructor for this type.

impl FromFd for OwnedFd

fn from_fd(owned: OwnedFd) -> Self

Constructs a new instance of Self from the given file descriptor.

fn from_into_fd<Owned: IntoFd>(into_owned: Owned) -> Self where
    Self: Sized, 

Constructs a new instance of Self from the given file descriptor converted from into_owned.

impl FromRawFd for OwnedFd

unsafe fn from_raw_fd(fd: RawFd) -> Self

Constructs a new instance of Self from the given raw file descriptor.

Safety

The resource pointed to by raw must be open and suitable for assuming ownership.

impl IntoFd for OwnedFd

fn into_fd(self) -> OwnedFd

Consumes this object, returning the underlying file descriptor.

impl IntoRawFd for OwnedFd

fn into_raw_fd(self) -> RawFd

Consumes this object, returning the raw underlying file descriptor.
