Pipelined peers

runPipelinedPeerWithLimits ∷ ∀ ps (st ∷ ps) pr failure bytes m a. (MonadAsync m, MonadFork m, MonadMask m, MonadThrow (STM m), MonadTimer m, ∀ (st' ∷ ps). Show (ClientHasAgency st'), ∀ (st' ∷ ps).

Run a pipelined peer with the given channel via the given codec.

This runs the peer to completion (if the protocol allows for termination).

Unlike normal peers, running pipelined peers rely on concurrency, hence the MonadAsync constraint.

Driver utilities
