zigar.function.Promise(T) - chung-leong/zigar GitHub Wiki

Define a promise type that will act as an interface to a JavaScript promise object. Typically, T is going to be an error union. When resolve() is called with a value, then the promise will be fulfilled with that value on the JavaScript side. When the function is given an error instead, then a rejection occurs.
