Struct ScheduledTask 

pub struct ScheduledTask {
    pub deadline: Instant,
    pub sequence: usize,
    pub state: Arc<AtomicU8>,
    pub task: Option<Box<dyn FnOnce() + Send + 'static>>,
}

Task stored in the delayed scheduler heap.

Fields

deadline: Instant

Time at which this task becomes runnable.

sequence: usize

Insertion order used to make equal deadlines deterministic.

state: Arc<AtomicU8>

Shared task state observed by cancellation handles.

task: Option<Box<dyn FnOnce() + Send + 'static>>

Scheduled action.

Implementations

impl ScheduledTask

pub fn new( deadline: Instant, sequence: usize, state: Arc<AtomicU8>, task: Box<dyn FnOnce() + Send + 'static>, ) -> Self

Creates a heap entry for a delayed task.

Parameters

• deadline - Instant when the task becomes runnable.
• sequence - Stable insertion sequence.
• state - Shared task lifecycle state.
• task - Action to run when the deadline is reached.

Returns

A scheduled task heap entry.

Trait Implementations

impl Ord for ScheduledTask

fn cmp(&self, other: &Self) -> CompareOrdering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for ScheduledTask

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

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

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

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

impl PartialOrd for ScheduledTask

fn partial_cmp(&self, other: &Self) -> Option<CompareOrdering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
