Struct Transitioning 

pub struct Transitioning<T: StyleInterpolatable> { /* private fields */ }

A single property undergoing a timed transition.

Holds the prior value, the target value, and the timing window. Call resolve each frame to get the interpolated output.

Implementations

impl<T: StyleInterpolatable> Transitioning<T>

pub fn new(prior: T, target: T, now: f64, spec: &TransitionSpec) -> Self

Create a new transition.

• prior: the value before the change.
• target: the new value.
• now: current monotonic time (seconds).
• spec: transition timing.

pub fn settled(value: T) -> Self

Create a completed (instant) transition.

pub fn resolve(&self, now: f64) -> T

Resolve the current interpolated value.

pub fn is_active(&self, now: f64) -> bool

Returns true when the transition is still in progress.

pub fn target(&self) -> &T

The target value (what we’re transitioning toward).

pub fn retarget(&mut self, new_target: T, now: f64, spec: &TransitionSpec)

Update the target, restarting the transition from the current interpolated value.

Trait Implementations

impl<T: Clone + StyleInterpolatable> Clone for Transitioning<T>

fn clone(&self) -> Transitioning<T>

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<T: Debug + StyleInterpolatable> Debug for Transitioning<T>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
