Struct FabView 

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

A declarative M3E FAB. See the module docs.

Implementations

impl<State: 'static> FabView<State>

pub fn size(self, size: FabSize) -> Self

Set the container size tier (fab only — ignored on an extended_fab, whose height is always EXTENDED_HEIGHT).

pub fn color(self, color: FabColor) -> Self

Set the container color tier (both variants).

pub fn icon(self, icon: impl View<State>) -> Self

Attach a leading icon (usable on extended_fab; fab already requires one at construction).

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

Attach an accessible label (fab’s content description). A no-op override on an extended_fab, whose visible label is already the accessible name.

pub fn extended(self, extended: bool) -> Self

Whether the label is shown (only meaningful on an extended_fab — a no-op on a plain fab, which has no label to show). Defaults to true. Setting false animates the label away, collapsing the pill toward an icon-only shape — see the module docs’ Extended FAB section.

pub fn corner_radius(self, radius: Option<f64>) -> Self

Override the corner radius (fab only — a no-op on extended_fab; see the module docs’ Corner-radius override seam section). None (the default) resolves the size-derived themed radius, easing toward a changed target with MaterialMotion::SHORT_4; Some(r) pins the radius to r immediately every frame, with no internal animation.

Trait Implementations

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

type Element = FabWidget

The retained widget this view produces.

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

Materialise a fresh widget for this view.

fn rebuild( &self, prev: &Self, element: &mut FabWidget, 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 FabWidget, 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.
