class (IsCap c, IsStruct p, IsStruct r) => HasMethod (name :: Symbol) c p r | name c -> p r where Source #

An instance HasMethod name c p r indicates that the interface type c has a method named name with parameter type p and return type r. The generated code includes instances of this for each method in the schema.

pipe :: (IsStruct a, ReprFor b ~ 'Ptr pr) => Field k a b -> Pipeline a -> Pipeline b Source #

Project a pipeline to a struct onto one of its pointer fields.

pipelineClient :: (IsCap a, MonadSTM m) => Pipeline a -> m (Client a) Source #

Convert a Pipeline for a capability into a Client.

waitPipeline :: forall a m pr. ('Ptr pr ~ ReprFor a, IsPtrRepr pr, MonadSTM m) => Pipeline a -> m (Raw 'Const a) Source #

Wait for the result of a pipeline, and return its value.

class AsClient f where Source #

The AsClient class allows callers of rpc methods to abstract over Clients and Pipelines. asClient converts either of those to a client so that methods can be invoked on it.
