The type for the connections returned by Self::connect().

type Listener = <MockNetProvider as NetStreamProvider>::Listener

The type for the listeners returned by Self::listen().

fn block_advance<T: Into<String>>(&self, reason: T)

Signify that a test running under mock time shouldn’t advance time yet, with a given unique reason string. This is useful for making sure (mock) time doesn’t advance while things that might require some (real-world) time to complete do so, such as spawning a task on another thread.

fn release_advance<T: Into<String>>(&self, reason: T)

Signify that the reason to withhold time advancing provided in a call to block_advance no longer exists, and it’s fine to move time forward if nothing else is blocking advances.

fn allow_one_advance(&self, dur: Duration)

Allow a test running under mock time to advance time by the provided duration, even if the above block_advance API has been used.
