pub struct Async<'l, F: AsRawFd> { /* private fields */ }Expand description
Adapter for async IO manipulations
This type wraps an IO object, providing methods to create futures waiting for its readiness.
If the futures-io cargo feature is enabled, it also implements AsyncRead and/or
AsyncWrite if the underlying type implements Read and/or Write.
Note that this adapter and the futures procuded from it and not threadsafe.
Implementations§

impl<'l, F: AsRawFd> Async<'l, F>
sourcepub fn readable<'s>(&'s mut self) -> Readable<'s, 'l, F> ⓘ
pub fn readable<'s>(&'s mut self) -> Readable<'s, 'l, F> ⓘ
A future that resolves once the object becomes ready for reading
sourcepub fn writable<'s>(&'s mut self) -> Writable<'s, 'l, F> ⓘ
pub fn writable<'s>(&'s mut self) -> Writable<'s, 'l, F> ⓘ
A future that resolves once the object becomes ready for writing
sourcepub fn into_inner(self) -> F
pub fn into_inner(self) -> F
