interface Future

A value that is both an Operation and Promise.

Futures are operations that are implicitly associated with an Effection scope and so they can be freely awaited within any async functions. However, they can also be evaluated directly within another operation, so among other things, if the operation resolves synchronously, it will continue within the same tick of the run loop.

Examples

Example 1

let task = run(function* () {
  return 42;
});

// in an effection scope
let valueFromYield = yield* task;
// in an async function
let valueFromAwait = await task;
