Struct style::traversal_flags::TraversalFlags

pub struct TraversalFlags { /* fields omitted */ }

Flags that control the traversal process.

Methods

impl TraversalFlags

pub const AnimationOnly: TraversalFlags

AnimationOnly: TraversalFlags = TraversalFlags{bits: 1 << 0,}

Traverse only elements for animation restyles.

pub const ForCSSRuleChanges: TraversalFlags

ForCSSRuleChanges: TraversalFlags = TraversalFlags{bits: 1 << 1,}

Traverse and update all elements with CSS animations since @keyframes rules may have changed. Triggered by CSS rule changes.

pub const Forgetful: TraversalFlags

Forgetful: TraversalFlags = TraversalFlags{bits: 1 << 3,}

A forgetful traversal ignores the previous state of the frame tree, and thus does not compute damage or maintain other state describing the styles pre-traversal. A forgetful traversal is usually the right thing if you aren't going to do a post-traversal.

pub const ClearDirtyBits: TraversalFlags

ClearDirtyBits: TraversalFlags = TraversalFlags{bits: 1 << 5,}

Clears all the dirty bits on the elements traversed.

pub const ClearAnimationOnlyDirtyDescendants: TraversalFlags

ClearAnimationOnlyDirtyDescendants: TraversalFlags = TraversalFlags{bits: 1 << 6,}

Clears the animation-only dirty descendants bit in the subtree.

pub const ParallelTraversal: TraversalFlags

ParallelTraversal: TraversalFlags = TraversalFlags{bits: 1 << 7,}

Allows the traversal to run in parallel if there are sufficient cores on the machine.

pub const FlushThrottledAnimations: TraversalFlags

FlushThrottledAnimations: TraversalFlags = TraversalFlags{bits: 1 << 8,}

Flush throttled animations. By default, we only update throttled animations when we have other non-throttled work to do. With this flag, we unconditionally tick and process them.

pub fn empty() -> TraversalFlags

Returns an empty set of flags.

pub fn all() -> TraversalFlags

Returns the set containing all flags.

pub fn bits(&self) -> u32

Returns the raw value of the flags currently stored.

pub fn from_bits(bits: u32) -> Option<TraversalFlags>

Convert from underlying bit representation, unless that representation contains bits that do not correspond to a flag.

pub fn from_bits_truncate(bits: u32) -> TraversalFlags

Convert from underlying bit representation, dropping any bits that do not correspond to flags.

pub fn is_empty(&self) -> bool

Returns true if no flags are currently stored.

pub fn is_all(&self) -> bool

Returns true if all flags are currently set.

pub fn intersects(&self, other: TraversalFlags) -> bool

Returns true if there are flags common to both self and other.

pub fn contains(&self, other: TraversalFlags) -> bool

Returns true all of the flags in other are contained within self.

pub fn insert(&mut self, other: TraversalFlags)

Inserts the specified flags in-place.

pub fn remove(&mut self, other: TraversalFlags)

Removes the specified flags in-place.

pub fn toggle(&mut self, other: TraversalFlags)

Toggles the specified flags in-place.

pub fn set(&mut self, other: TraversalFlags, value: bool)

Inserts or removes the specified flags depending on the passed value.

impl TraversalFlags

pub fn for_animation_only(&self) -> bool

Returns true if the traversal is for animation-only restyles.
