runRequesterT :: (Reflex t, Monad m) => RequesterT t request response m a -> Event t (RequesterData response) -> m (a, Event t (RequesterData request)) Source #

Run a RequesterT action. The resulting Event will fire whenever requests are made, and responses should be provided in the input Event. The Tag keys will be used to return the responses to the same place the requests were issued.

withRequesterT Source #

Arguments

:: (Reflex t, MonadFix m)
=> (forall x. req x -> req' x)	The function to map over the request
-> (forall x. rsp' x -> rsp x)	The function to map over the response
-> RequesterT t req rsp m a	The internal `RequesterT` whose input and output will be transformed
-> RequesterT t req' rsp' m a	The resulting `RequesterT`

Map a function over the request and response of a RequesterT

Arguments

:: (MonadFix m, MonadHold t m, Reflex t)
=> (forall a. request a -> (rawRequest, rawResponse -> response a))	Given a request (from `Requester`), produces the wire format of the request and a function used to process the associated response
-> Event t (RequesterData request)	The outgoing requests
-> Event t (Int, rawResponse)	The incoming responses, tagged by an identifying key
-> m (Event t (Map Int rawRequest), Event t (RequesterData response))	A map of outgoing wire-format requests and an event of responses keyed by the `RequesterData` key of the associated outgoing request

Matches incoming responses with previously-sent requests and uses the provided request "decoder" function to process incoming responses.
