Struct lightning::util::wakers::Future

pub struct Future { /* private fields */ }

A simple future which can complete once, and calls some callback(s) when it does so.

Implementations

impl Future

pub fn register_callback(&self, callback: Box<dyn FutureCallback>)

Registers a callback to be called upon completion of this future. If the future has already completed, the callback will be called immediately.

This is not exported to bindings users, use the bindings-only register_callback_fn instead

pub fn wait(&self)

Available on crate feature std only.

Waits until this Future completes.

pub fn wait_timeout(&self, max_wait: Duration) -> bool

Available on crate feature std only.

Waits until this Future completes or the given amount of time has elapsed.

Returns true if the Future completed, false if the time elapsed.

Trait Implementations

impl Drop for Future

fn drop(&mut self)

Executes the destructor for this type.

impl<'a> Future for Future

This is not exported to bindings users as Rust Futures aren’t usable in language bindings.

type Output = ()

The type of value produced on completion.

fn poll(self: Pin<&mut Self>, cx: &mut Context<'_>) -> Poll<Self::Output>

Attempt to resolve the future to a final value, registering the current task for wakeup if the value is not yet available.
