Converts a Promise to a folktale Future.
Converts a Promise to a folktale Future.
Note that this conversion may not be as accurate due to the differences in Promise and Future semantics. In particular, Promises recursively flatten any object with a .then method, and do not have a separate representation for cancellations.
If a Promise contains a rejection with Folktale's special Cancelled() value, then the resulting Future will be a cancelled Future rather than a rejected one.
const { fromPromise } = require('folktale/concurrency/future');
fromPromise(Promise.resolve(1));
// => Future.resolve(1)
fromPromise(Promise.reject(1));
// => Future.reject(1)
fromPromise(aPromise) {
return require('folktale/conversions/promise-to-future')(aPromise);
}
