[−][src]Struct governor::RatelimitedStream
A [Stream][futures::Stream] combinator which will limit the rate of items being received.
This is produced by the StreamRateLimitExt::ratelimit_stream and
StreamRateLimitExt::ratelimit_stream_with_jitter methods.
Implementations
impl<'a, S: Stream, D: DirectStateStore, C: Clock> RatelimitedStream<'a, S, D, C>[src]
Conversion methods for the stream combinator.
pub fn get_ref(&self) -> &S[src]
Acquires a reference to the underlying stream that this combinator is pulling from.
pub fn get_mut(&mut self) -> &mut S[src]
Acquires a mutable reference to the underlying stream that this combinator is pulling from.
pub fn into_inner(self) -> (S, Option<S::Item>)[src]
Consumes this combinator, returning the underlying stream and any item which it has already produced but which is still being held back in order to abide by the limiter.
