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

fromEffectFnAff :: EffectFnAff ~> Aff

Lift a FFI definition into an Aff. EffectFnAff makes use of EffectFn so Effect 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 :: EffectFnAff String

myAff :: Aff String
myAff = fromEffectFnAff _myAff
