stm-conduit-2.0.0: Introduces conduits to channels, and promotes using conduits concurrently.

Safe HaskellNone

Data.Conduit.TQueue

Contents

Description

Contains a simple source and sink linking together conduits in different threads. For extended examples of usage and bottlenecks see TMChan.

TQueue is an amoritized FIFO queue behaves like TChan, with two important differences:

  • it's faster (but amortized thus the cost of individual operations may vary a lot)
  • it doesn't provide equivalent of the dupTChan and cloneTChan operations

Here is short description of data structures:

  • TQueue - unbounded infinite queue * TBQueue - bounded infinite queue * TMQueue - unbounded finite (closable) queue * TBMQueue - bounded finite (closable) queue

Caveats

Infinite operations means that source doesn't know when stream is ended so one need to use other methods of finishing stream like sending an exception or finish conduit in downstream.
