#[must_use = "streams do nothing unless polled"]
pub struct TryBufferUnordered<St> where
    St: TryStream
{ /* fields omitted */ }

A stream returned by the try_buffer_unordered method

Methods

impl<St> TryBufferUnordered<St> where
    St: TryStream,
    <St as TryStream>::Ok: TryFuture
[src]

Acquires a reference to the underlying stream that this combinator is pulling from.

Acquires a mutable reference to the underlying stream that this combinator is pulling from.

Note that care must be taken to avoid tampering with the state of the stream which may otherwise confuse this combinator.

Consumes this combinator, returning the underlying stream.

Note that this may discard intermediate state of this combinator, so care should be taken to avoid losing resources when this is called.
