Struct x11rb_async::utils::RawFdContainer

pub struct RawFdContainer(_);

A simple wrapper around RawFd that closes the fd on drop.

On non-unix systems, this type is empty and does not provide any method.

Implementations

impl RawFdContainer

pub fn new(fd: i32) -> RawFdContainer

Create a new RawFdContainer for the given RawFd.

The RawFdContainer takes ownership of the RawFd and closes it on drop.

pub fn try_clone(&self) -> Result<RawFdContainer, Error>

Tries to clone the RawFdContainer creating a new FD with dup. The new RawFdContainer will take ownership of the duped version, whereas the original RawFdContainer will keep the ownership of its FD.

pub fn into_raw_fd(self) -> i32

Get the RawFd out of this RawFdContainer.

This function would be an implementation of IntoRawFd if that were possible. However, it causes a conflict with an impl from libcore…

pub fn close(self) -> Result<(), Error>

Consumes the RawFdContainer and closes the wrapped FD with the close system call.

This is similar to dropping the RawFdContainer, but it allows the caller to handle errors.

Trait Implementations

impl AsRawFd for RawFdContainer

fn as_raw_fd(&self) -> i32

Extracts the raw file descriptor.

impl Debug for RawFdContainer

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

Formats the value using the given formatter.

impl Drop for RawFdContainer

fn drop(&mut self)

Executes the destructor for this type.

impl<T> From<T> for RawFdContainerwhere T: IntoRawFd,

fn from(fd: T) -> RawFdContainer

Converts to this type from the input type.

impl Hash for RawFdContainer

fn hash<__H>(&self, state: &mut __H)where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq<RawFdContainer> for RawFdContainer

fn eq(&self, other: &RawFdContainer) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
