Struct calloop::io::Async [−][src]
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>[src]
pub fn get_mut(&mut self) -> &mut F[src]
Mutably access the underlying IO object
pub fn readable<'s>(&'s mut self) -> Readable<'s, 'l, F>ⓘ[src]
A future that resolves once the object becomes ready for reading
pub fn writable<'s>(&'s mut self) -> Writable<'s, 'l, F>ⓘ[src]
A future that resolves once the object becomes ready for writing
pub fn into_inner(mut self: Self) -> F[src]
Remove the async adapter and retrieve the underlying object
