[−][src]Struct async_stdio::AsStdIo
Adapter to use an async byte stream as a std::io::{Read, Write}
type
For correct operation, WakerCtrl::register
must be called before any calls
to read
or write
. If the async stream would return Poll::Pending
, it
will be converted to an io::ErrorKind::WouldBlock
error.
Methods
impl<S> AsStdIo<S>
[src]
pub fn new(stream: S, waker: Option<&Waker>) -> (Self, WakerCtrl)
[src]
Wrap the async stream and initialize the wrapper with the provided waker.
If no waker is provided, it will be initialized with a no-op waker.
Also returns a handle that can be used to control the waker.
pub fn with_context<F, T>(&mut self, f: F) -> T where
F: for<'c> FnOnce(Pin<&mut S>, &mut Context<'c>) -> T,
S: Unpin,
[src]
F: for<'c> FnOnce(Pin<&mut S>, &mut Context<'c>) -> T,
S: Unpin,
Get a pinned reference to the internal stream and a context with which to poll it.
Sometimes useful if you need to perform some operation such as
[AsyncWrite::close] on it which doesn't have an std
counterpart.
