pub struct StyleReasonFlags(/* private fields */);

Implementations

impl StyleReasonFlags

pub const SELECTOR: Self

The view has style selectors (:hover, :focus, :disabled, etc.) whose matching result may have changed. Requires full resolve_nested_maps to re-run since selector matching depends on interaction state.

pub const ANIMATION: Self

One or more animations are actively running on this view. The animation stack needs to be advanced and animate_into applied to the combined style. Implies the view needs to be scheduled for the next frame via schedule_style.

pub const TRANSITION: Self

A CSS-style property transition is in progress (e.g. background color, opacity). The transition interpolator needs to be stepped and its output applied to the view style props (view_style_props.read_explicit). Implies schedule_style.

pub const TARGET: Self

One or more specific sub-element rectangles owned by this view need restyling, identified by their ElementId. Used when a view owns multiple ElementIds (e.g. a scroll view’s content area, vertical scrollbar, horizontal scrollbar) and only a subset need to be updated. The targets vec carries each affected ElementId and the StyleReasonSet describing why that specific element is dirty, allowing style_pass to dispatch targeted updates rather than fully restyling the entire view.

pub const STYLE_PASS: Self

Request that the style_pass be run again.

pub const VIEW_STYLE: Self

Request that the view_style method from the View trait be run again.

pub const VISIBILITY: Self

Request that the style_pass be run again

pub const INHERITED_CHANGE: Self

Parent’s inherited scalar properties changed (font size, color, etc.). Child must recompute computed_style but may skip resolve_nested_maps if it has no selectors and its own style stack is clean.

pub const CLASS_CONTEXT_CHANGE: Self

Parent’s class context map changed (new class definitions visible to children). Child must re-run resolve_nested_maps to pick up new class rules, but inherited scalar props are unchanged so with_context values are stable.

impl StyleReasonFlags

pub const fn empty() -> Self

Get a flags value with all bits unset.

pub const fn all() -> Self

Get a flags value with all known bits set.

Get the underlying bits value.

The returned value is exactly the bits set in this flags value.

Convert from a bits value exactly.

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

The bitwise or (|) of the bits in two flags values.

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

The intersection of a source flags value with the complement of a target flags value (&!).

This method is not equivalent to self & !other when other has unknown bits set. remove won’t truncate other, but the ! operator will.

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

The bitwise exclusive-or (^) of the bits in two flags values.

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

Call insert when value is true or remove when value is false.

pub const fn union(self, other: Self) -> Self

The bitwise or (|) of the bits in two flags values.

pub const fn difference(self, other: Self) -> Self

The intersection of a source flags value with the complement of a target flags value (&!).

This method is not equivalent to self & !other when other has unknown bits set. difference won’t truncate other, but the ! operator will.

pub const fn symmetric_difference(self, other: Self) -> Self

The bitwise exclusive-or (^) of the bits in two flags values.

pub const fn complement(self) -> Self

The bitwise negation (!) of the bits in a flags value, truncating the result.

impl StyleReasonFlags

pub const fn iter(&self) -> Iter<StyleReasonFlags>

Yield a set of contained flags values.

Each yielded flags value will correspond to a defined named flag. Any unknown bits will be yielded together as a final flags value.

pub const fn iter_names(&self) -> IterNames<StyleReasonFlags>

Yield a set of contained named flags values.

This method is like iter, except only yields bits in contained named flags. Any unknown bits, or bits not corresponding to a contained flag will not be yielded.
