Polysemy.Process.ProcessOutput

Description

The utility effect ProcessOutput takes care of decoding process output, getting called by the Process interpreters whenever a chunk was read, while accumulating chunks until they were decoded successfully.

Synopsis

Documentation

data ProcessOutput a :: Effect where Source #

This effect is used by the effect Process to accumulate and decode chunks of ByteStrings, for example using a parser. The interpreter may be stateful or stateless, since the constructor Chunk is expected to be called with both the accumulated unprocessed output as well as the new chunk.

Constructors

Chunk

Add a chunk of output to the accumulator, returning any number of successfully parsed values and the leftover output.
