Struct Delay

pub struct Delay { /* private fields */ }

The Delay future represents an asynchronous sleep.

Implementations

impl Delay

pub fn new(when: Instant) -> Self

pub fn decrease(&mut self, duration: Duration)

Adjusts the delay to be duration earlier.

pub fn increase(&mut self, duration: Duration)

Adjusts the delay to be duration later.

pub fn waker(&self) -> Option<Arc<Mutex<Waker>>>

Returns the Waker that will be notified when the delay completes.

pub fn when(&self) -> Instant

Returns the Instant at which the delay will complete.

Trait Implementations

impl Clone for Delay

fn clone(&self) -> Delay

Returns a duplicate of the value.

const fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Delay

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for Delay

fn default() -> Self

Returns the “default value” for a type.

impl Future for Delay

type Output = ()

The type of value produced on completion.

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

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

impl PartialEq for Delay

fn eq(&self, other: &Self) -> bool

Tests for self and other values to be equal, and is used by ==.

const fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
