Types

cmdContSP :: a -> (b -> Maybe c) -> Cont (SP b a) c
cmdContK :: FRequest -> (FResponse -> Maybe a) -> Cont (K b c) a
cmdContF :: FRequest -> (FResponse -> Maybe a) -> Cont (F b c) a
cmdContLow :: FudgetIO f =>
              FRequest -> (FResponse -> Maybe ans) -> (ans -> f hi ho) -> f hi ho
waitForSP :: (a -> Maybe t) -> (t -> SP a b) -> SP a b
dropSP :: (t1 -> Maybe t2) -> (t2 -> SP t1 b) -> SP t1 b

Synopsis

cmdContSP request expected contf

Description

The cmdCont functions are used when you want to output a message and wait for a particular response. Except dropSP, other input is queued up until the expected input is received.

waitForSP can be used when you just want to wait for a particular message, without outputting something first.

dropSP is like waitForSP, except that it will not queue other input.

Arguments

request :: a
The request to output
expected :: b -> Maybe c
A function to test input messages with. It should return Just x for the response you are waiting for and Nothing otherwise.
contf :: ??
The stream processor to continue with, parameterized by the response picked out by expected.
