Struct BadgeView 

pub struct BadgeView<State: 'static> { /* private fields */ }

A declarative badge wrapping any child view. See the module docs.

Implementations

impl<State: 'static> BadgeView<State>

pub fn dot(self) -> Self

Show an unlabeled dot — wins over Self::count if both are set.

pub fn count(self, count: u32) -> Self

Show a numeric label, formatted against Self::max_count (default [DEFAULT_MAX_COUNT], 99 — e.g. 150 paints "99+").

pub fn max_count(self, max_count: u32) -> Self

Override the overflow ceiling Self::count formats against. [DEFAULT_MAX_COUNT] (99) unless set.

pub fn alignment(self, alignment: BadgeAlignment) -> Self

Anchor the indicator at a different top-edge corner. BadgeAlignment::TopRight by default.

pub fn offset(self, offset: Vec2) -> Self

Override the nudge away from the anchored edge. [DEFAULT_OFFSET] ((8, -6)) unless set; dx is ignored when BadgeAlignment::TopCenter.

pub fn background_color(self, color: Color) -> Self

Override the theme-resolved errorContainer container fill.

pub fn foreground_color(self, color: Color) -> Self

Override the theme-resolved onErrorContainer label/dot ink.

pub fn semantic_label(self, label: impl Into<String>) -> Self

Override the indicator’s accessibility label. Defaults to "Notifications: {count}" for a numeric badge or "Notifications" for a dot (the reference’s own default label text).

Trait Implementations

impl<State: 'static> View<State> for BadgeView<State>

type Element = BadgeWidget

fn build(&self, ctx: &mut BuildCtx<'_>) -> BadgeWidget

Materialise a fresh widget for this view.

fn rebuild( &self, prev: &Self, element: &mut BadgeWidget, ctx: &mut BuildCtx<'_>, ) -> ChangeFlags

Reconcile prev (the previous view of the same type) against the live element, mutating it in place and reporting what changed.

fn teardown(&self, element: &mut BadgeWidget, ctx: &mut BuildCtx<'_>)

Tear down element when this view is being removed.

fn message(&self, _element: &mut Self::Element, _state: &mut State)

Deliver an event message to this view, mutating application state.
