Control.Monad.Aff.Compat

Package: purescript-aff
Repository: slamdata/purescript-aff

This module provides compatability functions for constructing Affs which are defined via the FFI.

#EffFnAff Source

newtype EffFnAff eff a

Constructors

EffFnAff (EffFn2 eff (EffFnCb eff Error) (EffFnCb eff a) (EffFnCanceler eff))

#EffFnCanceler Source

newtype EffFnCanceler eff

Constructors

EffFnCanceler (EffFn3 eff Error (EffFnCb eff Error) (EffFnCb eff Unit) Unit)

#EffFnCb Source

type EffFnCb eff a = EffFn1 eff a Unit

#fromEffFnAff Source

fromEffFnAff :: forall a eff. EffFnAff eff a -> Aff eff a

Lift a FFI definition into an Aff. EffFnAff makes use of EffFn so Eff thunks are unnecessary. A definition might follow this example:

exports._myAff = function (onError, onSuccess) {
  var cancel = doSomethingAsync(function (err, res) {
    if (err) {
      onError(err);
    } else {
      onSuccess(res);
    }
  });
  return function (cancelError, onCancelerError, onCancelerSuccess) {
    cancel();
    onCancelerSuccess();
  };
};

foreign import _myAff :: forall eff. EffFnAff (myeffect :: MYEFFECT | eff) String

myAff :: forall eff. Aff (myeffect :: MYEFFECT | eff) String
myAff = fromEffFnAff _myAff
