Struct Dirty 

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

What changed since the decoration was last drawn.

Reserved for a partial-redraw path, as upstream reserves it: Renderer::draw reads none of these bits today and repaints the whole decoration whatever is set.

A bitmask rather than a bool so a caller can already record what changed: redrawing a title bar because the pointer moved over a button needs only a rounded-rect fill, while redrawing it because the geometry changed needs a blur, and a bool could not tell the two apart.

Implementations

impl Dirty

pub const NONE: Self

Nothing changed.

pub const TITLE: Self

The title text.

Focus.

pub const HOVER: Self

Which button is hovered.

pub const GEOMETRY: Self

The window’s size or position.

pub const ANIMATION: Self

An animation advanced.

pub const ALL: Self

Everything. What a freshly created state carries, since nothing has been drawn yet and every part of it is new.

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

Whether any of other’s bits are set here.

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

Both sets of bits.

pub const fn is_empty(self) -> bool

Whether nothing is set.
