[−][src]Enum core::task::Poll
🔬 This is a nightly-only experimental API. (futures_api #50547)
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
Ready(T)🔬 This is a nightly-only experimental API. (futures_api #50547)
futures in libcore are unstable
Represents that a value is immediately ready.
Pending🔬 This is a nightly-only experimental API. (futures_api #50547)
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.
