Expand description

Converts a futures 0.3 TryFuture or TryStream into a futures 0.1 Future or Stream.

Implementations

Creates a new Compat.

For types which implement appropriate futures 0.3 traits, the result will be a type which implements the corresponding futures 0.1 type.

Get a reference to 0.3 Future, Stream, AsyncRead, or AsyncWrite object contained within.

Get a mutable reference to 0.3 Future, Stream, AsyncRead, or AsyncWrite object contained within.

Returns the inner item.
