race_ :: Member Race r => Sem r a -> Sem r a -> Sem r a Source #

Specialization of race for the case where both actions return the same type, obviating the need for Either.

timeout_ :: TimeUnit u => Member Race r => Sem r a -> u -> Sem r a -> Sem r a Source #

Specialization of timeout for the case where the main action returns the same type as the fallback, obviating the need for Either.

timeoutAs :: TimeUnit u => Member Race r => a -> u -> Sem r b -> Sem r (Either a b) Source #

Version of timeout that takes a pure fallback value.

timeoutAs_ :: TimeUnit u => Member Race r => a -> u -> Sem r a -> Sem r a Source #

Specialization of timeoutAs for the case where the main action return the same type as the fallback, obviating the need for Either.

timeoutU :: TimeUnit u => Member Race r => u -> Sem r () -> Sem r () Source #

Specialization of timeout for unit actions.

timeoutMaybe :: TimeUnit u => Member Race r => u -> Sem r a -> Sem r (Maybe a) Source #

Variant of timeout that returns Maybe.

timeoutStop :: TimeUnit u => Members [Race, Stop err] r => err -> u -> Sem r a -> Sem r a Source #

Variant of timeout that calls Stop with the supplied error when the action times out.
