impl<Request> BufferLayer<Request>

const fn new(bound: usize) -> Self

Creates a new BufferLayer with the provided bound.

bound gives the maximal number of requests that can be queued for the service before backpressure is applied to callers.

A note on choosing a bound

When Buffer's implementation of poll_ready returns Poll::Ready, it reserves a slot in the channel for the forthcoming call. However, if this call doesn't arrive, this reserved slot may be held up for a long time. As a result, it's advisable to set bound to be at least the maximum number of concurrent requests the Buffer will see. If you do not, all the slots in the buffer may be held up by futures that have just called poll_ready but will not issue a call, which prevents other senders from issuing new requests.
