Enum LifecycleState 

pub enum LifecycleState {
    VisualUpdatePending,
    InStyleRecalc,
    StyleClean,
    InLayout,
    LayoutClean,
    InPrePaint,
    PrePaintClean,
    InPaint,
    PaintClean,
}

The current lifecycle state of a document.

Chrome: DocumentLifecycle::LifecycleState.

Variants

VisualUpdatePending

Something visual changed — needs work.

InStyleRecalc

Style recalc is running.

StyleClean

Styles computed — ready for layout.

InLayout

Layout is running.

LayoutClean

Layout complete — ready for paint.

InPrePaint

Pre-paint (paint property trees) is running.

PrePaintClean

Pre-paint complete.

InPaint

Paint (display list generation) is running.

PaintClean

All phases complete — everything clean.

Implementations

impl LifecycleState

pub fn is_clean(self) -> bool

Whether this state is “clean” (not in the middle of a phase).

pub fn is_layout_clean(self) -> bool

Whether layout results are up-to-date.

pub fn is_paint_clean(self) -> bool

Whether paint results are up-to-date.

pub fn invalidate(&mut self)

Mark that a visual update is needed (invalidate all phases).

Chrome: DocumentLifecycle::SetVisualUpdatePending(). Called when DOM changes, style changes, or viewport resizes.

pub fn needs_update(self) -> bool

Whether any work needs to be done.

Trait Implementations

impl Clone for LifecycleState

fn clone(&self) -> LifecycleState

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for LifecycleState

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

Formats the value using the given formatter.

impl Default for LifecycleState

fn default() -> LifecycleState

Returns the “default value” for a type.

impl Ord for LifecycleState

fn cmp(&self, other: &LifecycleState) -> 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.

impl PartialEq for LifecycleState

fn eq(&self, other: &LifecycleState) -> 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 LifecycleState

fn partial_cmp(&self, other: &LifecycleState) -> 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.
