pub struct Buffer<Si, Item> { /* private fields */ }
Expand description

Sink for the buffer method.

Implementations§

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

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

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

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

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

Consumes this combinator, returning the underlying sink or stream.

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

Returns true if the stream should no longer be polled.
The type of value produced by the sink when an error occurs.
Attempts to prepare the Sink to receive a value. Read more

Flush any remaining output from this sink. Read more
Flush any remaining output and close this sink, if necessary. Read more
Values yielded by the stream.
Attempt to pull out the next value of this stream, registering the current task for wakeup if the value is not yet available, and returning None if the stream is exhausted. Read more
Returns the bounds on the remaining length of the stream. Read more
