Struct DispatcherPriority 

pub struct DispatcherPriority { /* private fields */ }

Defines the priorities with which jobs can be invoked on a Dispatcher.

Implementations

impl DispatcherPriority

pub const DEFAULT: Self

The lowest foreground dispatcher priority.

pub const INPUT: Self

The job will be processed with the same priority as input.

pub const BACKGROUND: Self

The job will be processed after other non-idle operations have completed.

pub const CONTEXT_IDLE: Self

The job will be processed after background operations have completed.

pub const APPLICATION_IDLE: Self

The job will be processed when the application is idle.

pub const SYSTEM_IDLE: Self

The job will be processed when the system is idle.

pub const INACTIVE: Self

A dispatcher priority for jobs that shouldn’t be executed yet.

pub const INVALID: Self

Used internally in dispatcher code.

pub const LOADED: Self

The job will be processed after layout and render but before input.

pub const UI_THREAD_RENDER: Self

A special priority for platforms with a UI render timer or for forced full rasterization requests.

pub const AFTER_RENDER: Self

A special priority to synchronize native control host positions, IME, etc. Renderer results have to be reported before any user code and most of the system input callbacks.

pub const RENDER: Self

The job will be processed with the same priority as render.

pub const BEFORE_RENDER: Self

A special platform hook for jobs to be executed before the normal render cycle.

pub const ASYNC_RENDER_TARGET_RESIZE: Self

A special priority for platforms that resize the render target in asynchronous-commit mode.

pub const DATA_BIND: Self

👎Deprecated:

WPF compatibility

The job will be processed with the same priority as data binding.

pub const NORMAL: Self

The job will be processed with normal priority.

pub const SEND: Self

The job will be processed before other asynchronous operations.

pub const MAX_VALUE: Self = Self::SEND

Maximum possible priority.

pub const fn value(self) -> i32

The numeric value of the priority.

pub fn from_value(value: i32) -> Self

Creates a priority from its numeric value.

Panics

Panics when value is outside the valid range; use TryFrom<i32> for untrusted input.

pub fn validate(priority: DispatcherPriority, parameter_name: &str)

Verifies that priority can be used to queue work.

Panics

Panics when the priority is outside INACTIVE..=MAX_VALUE.

Trait Implementations

impl Clone for DispatcherPriority

fn clone(&self) -> Self

Returns a duplicate of the value.

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

impl Eq for DispatcherPriority

impl From<DispatcherPriority> for i32

fn from(priority: DispatcherPriority) -> i32

Converts to this type from the input type.

impl Ord for DispatcherPriority

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

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.

fn clamp_to<R>(self, range: R) -> Self

where Self: Sized, R: ClampBounds<Self>,

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

Restrict a value to a certain range.

impl PartialEq for DispatcherPriority

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

Equality operator ==.

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

Inequality operator !=.

impl PartialOrd for DispatcherPriority

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

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.

impl StructuralPartialEq for DispatcherPriority

impl TryFrom<i32> for DispatcherPriority

type Error = DispatcherPriorityOutOfRangeError

fn try_from(value: i32) -> Result<Self, Self::Error>

Performs the conversion.
