ZChannel

sealed trait ZChannel[-Env, -InErr, -InElem, -InDone, +OutErr, +OutElem, +OutDone]

A ZChannel[In, Env, Err, Out, Z] is a nexus of I/O operations, which supports both reading and writing. A channel may read values of type In and write values of type Out. When the channel finishes, it yields a value of type Z. A channel may fail with a value of type Err.

Channels are the foundation of ZIO Streams: both streams and sinks are built on channels. Most users shouldn't have to use channels directly, as streams and sinks are much more convenient and cover all common use cases. However, when adding new stream and sink operators, or doing something highly specialized, it may be useful to use channels directly.

Channels compose in a variety of ways:

  • Piping. One channel can be piped to another channel, assuming the input type of the second is the same as the output type of the first.
  • Sequencing. The terminal value of one channel can be used to create another channel, and both the first channel and the function that makes the second channel can be composed into a channel.
  • Concating. The output of one channel can be used to create other channels, which are all concatenated together. The first channel and the function that makes the other channels can be composed into a channel.
