pub struct CrossFade<K> { /* private fields */ }

Implementations

impl<K> CrossFade<K>

where K: Clone + PartialEq,

pub const SPEC: MotionSpec = CROSS_FADE

pub fn new(shown: K) -> CrossFade<K>

Showing shown, at rest.

pub fn show( &mut self, next: K, motion: EffectiveMotion, source: MotionSource, now: Instant, )

Show next; a no-op when it is already shown.

pub fn arrive(&mut self, next: K, motion: EffectiveMotion, now: Instant)

Show next, data that arrived (a read’s answer replacing its placeholder): no hand caused it, so it fades at fast rather than landing or waiting on input; a no-op when already shown.

pub fn shown(&self) -> &K

What is shown (the newest content).

pub fn outgoing(&self, now: Instant) -> Option<(&K, f32)>

The outgoing content and its opacity, while it still shows.

pub fn incoming(&self, now: Instant) -> f32

The incoming (shown) content’s opacity.

pub fn is_moving(&self, now: Instant) -> bool

pub fn settles_at(&self) -> Option<Instant>
