std:std.fiber.Future<T>

Class Future<T>

Futures provide support for simple fiber synchronization.

A future allows you to synchronize two fibers by providing a way for one fiber to signal to another that an operation has completed.

The general usage pattern of futures is:

• Fiber A creates a future and passes it to fiber B.

• Fiber A then calls Get on the future. This will suspend Fiber A.

• Fiber B performs some operation, then calls Set on the future. This will resume Fiber A.

A future can only be set once.
