pub struct HintLayer<S>
where
    S: 'static,
{ /* private fields */ }

A host’s set of control hints, scheduled and drawn.

Implementations

impl<S> HintLayer<S>

where S: Copy + PartialEq + 'static,

pub fn new(specs: &'static [HintSpec<S>], learned: Learned) -> HintLayer<S>

pub fn coach(&self) -> &Coach<S>

pub fn coach_mut(&mut self) -> &mut Coach<S>

pub fn update( &mut self, now: Instant, holds: &dyn Fn(S) -> bool, quiet: Option<Quiet>, place: &dyn Fn(&HintSpec<S>) -> Option<HintPlace>, motion: EffectiveMotion, )

Advance to now: holds and quiet as Coach::tick takes them, place how each hint would show now (None where its anchor is not on screen).

pub fn needs_frame(&self, now: Instant, motion: EffectiveMotion) -> bool

Whether the hint on screen moves at now.

pub fn next_wake( &self, now: Instant, motion: EffectiveMotion, ) -> Option<Instant>

When the layer next needs a frame: soon while a hint moves, at the schedule’s next change otherwise.

pub fn card_rect(&self) -> Option<Rect>

The card as last drawn, for hit tests and capture checks.

pub fn painted_rect(&self) -> Option<Rect>

Everything the last draw painted (the card with its shadow, a lit edge, the dot it folds into and where that lands): while the hint moves, the only pixels it changes are under this and the last draw’s.

pub fn access_node(&self) -> Option<AccessNode>

The hint for assistive technology: its words and keys, said politely when it comes.

pub fn draw( &mut self, scene: &mut Scene, transform: Affine, text: &mut TextRenderer, theme: &Theme, now: Instant, look: &HintLook, )

Draw the hint on screen at now.
