source · pub struct RWHandle<T> { /* private fields */ }
Expand description
A Handle
that receives notifications when it is readable/writable.
Implementations§
source§impl<T> RWHandle<T>where
T: AsHandleRef,
impl<T> RWHandle<T>where T: AsHandleRef,
sourcepub fn new(handle: T) -> Result<Self, Status>
pub fn new(handle: T) -> Result<Self, Status>
Creates a new RWHandle
object which will receive notifications when
the underlying handle becomes readable, writable, or closes.
sourcepub fn into_inner(self) -> T
pub fn into_inner(self) -> T
Consumes self
and returns the underlying handle.

&self,
cx: &mut Context<'_>
) -> Poll<Result<ReadableState, Status>>
fn poll_readable( &self, cx: &mut Context<'_> ) -> Poll<Result<ReadableState, Status>>
If the object is ready for reading, returns
Ready
with the readable
state. If the implementor returns Pending, it should first ensure that
need_readable
is called. Read moresource§impl<T> WritableHandle for RWHandle<T>where

fn poll_writable( &self, cx: &mut Context<'_> ) -> Poll<Result<WritableState, Status>>
If the object is ready for writing, returns
Ready
with the writable
state. If the implementor returns Pending, it should first ensure that
need_writable
is called. Read moreAuto Trait Implementations§
