Enum futures::prelude::Poll[][src]

pub enum Poll<T> {
    Ready(T),
    Pending,
}
🔬 This is a nightly-only experimental API. (futures_api)

futures in libcore are unstable

Indicates whether a value is available or if the current task has been scheduled to receive a wakeup instead.

Variants

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

futures in libcore are unstable

Represents that a value is immediately ready.

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

futures in libcore are unstable

Represents that a value is not ready yet.

When a function returns Pending, the function must also ensure that the current task is scheduled to be awoken when progress can be made.
