🔬 This is a nightly-only experimental API. (futures_api)

futures in libcore are unstable

[]

Spawns tasks that poll futures to completion onto its associated task executor.

The term "task" refers to a kind of lightweight "thread". Task executors are responsible for scheduling the execution of tasks on operating system threads.

Required Methods

[]

🔬 This is a nightly-only experimental API. (futures_api)

futures in libcore are unstable

Spawns a new task with the given future. The future will be polled until completion.

Errors

The executor may be unable to spawn tasks, either because it has been shut down or is resource-constrained.

Provided Methods

[]

🔬 This is a nightly-only experimental API. (futures_api)

futures in libcore are unstable

Determines whether the executor is able to spawn new tasks.

Returns

An Ok return means the executor is likely (but not guaranteed) to accept a subsequent spawn attempt. Likewise, an Err return means that spawn is likely, but not guaranteed, to yield an error.
