pub type OptionalStream<S> = Optional<S>;👎Deprecated: Use Optional instead
Expand description
A reusable stream that is the equivalent to an Option.
By default, this future will be empty, which would return [Poll::Pending] when polled,
but if a [Stream] is supplied either upon construction via OptionalStream::new or
is set via OptionalStream::replace, the stream could later polled once OptionalStream
is polled. Once the stream is polled to completion, OptionalStream will be empty.
Aliased Type§
pub struct OptionalStream<S> { /* private fields */ }
