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

Mutably access the underlying IO object

A future that resolves once the object becomes ready for reading

A future that resolves once the object becomes ready for writing

Remove the async adapter and retrieve the underlying object
