Struct Breadcrumb 

pub struct Breadcrumb<Msg> { /* private fields */ }

The path to the current place, such as workspace › quvyta › crates › src.

Every segment but the last opens its level; the last is the current place, bold and not clickable. Segments are bare text that rises on hover; the separator is a faint chevron icon. When the path does not fit, the middle collapses into …, which lists the hidden levels.

Keys while focused: ←/→ move between segments, Home/End jump to the ends, Enter or Space opens the segment (or the list behind …).

Style keys: crumb with hover, focus; crumb.current; crumb-separator; popup-menu, popup-item, popup-check for the hidden levels. Icon: crumb-separator.

Implementations

impl<Msg: 'static> Breadcrumb<Msg>

pub fn new(segments: impl IntoIterator<Item = impl Into<String>>) -> Self

A path of segments from the root to the current place.

pub fn on_select(self, message: impl Fn(usize) -> Msg + 'static) -> Self

Message for opening segment index.

Trait Implementations

impl<Msg: 'static> Widget<Msg> for Breadcrumb<Msg>

fn measure(&self, _cx: &mut MeasureCx<'_>, available: Size) -> Size

The size the widget wants when it may use up to available.

fn paint(&self, cx: &mut PaintCx<'_>, area: Rect)

Draws the widget into area.

fn paint_overlay(&self, cx: &mut PaintCx<'_>, anchor: Rect)

Draws the widget’s overlay after the whole view was painted, when it asked for one with PaintCx::request_overlay. anchor is the area the widget was painted in.

fn event(&self, cx: &mut EventCx<'_, Msg>, event: &Event) -> bool

Handles input. Returns true when the event was used; unused key and scroll events bubble to the parent widget.

fn focusable(&self) -> bool

Whether the widget can take keyboard focus.

fn children(&self) -> &[Node<Msg>]

Child nodes, for widgets that contain other widgets.

fn children_mut(&mut self) -> &mut [Node<Msg>]

Mutable child nodes, used to assign ids.
