Bluefin.Capability.ReturnEarly
Synopsis
- type ReturnEarly = Throw
- withReturnEarly :: forall r (es :: Effects). (forall (e :: Effects). ReturnEarly r e -> Eff (e :& es) r) -> Eff es r
- returnEarly :: forall (e :: Effects) (es :: Effects) r a. e <: es => ReturnEarly r e -> r -> Eff es a
Documentation
Bluefin.ReturnEarly allows to define a block from which you can
return early. Early return is implemented as an exception, and
its API is just an alternate interface to exceptions.
