Struct Motion 

pub struct Motion<T> { /* private fields */ }

A typed handle to an animation stored in a MotionRuntime.

Handles become invalid after their animation is removed.

Implementations

impl<T: Animatable> Motion<T>

pub fn transition_to(self, target: T, runtime: &mut MotionRuntime) -> bool

Transitions this motion toward target.

Returns false when the handle is no longer valid.

pub fn play( self, animation: impl Animation<T>, runtime: &mut MotionRuntime, ) -> bool

Replaces this motion’s current animation.

Returns false when the handle is no longer valid.

pub fn value(self, runtime: &MotionRuntime) -> T

Clones and returns the current value.

Panics

Panics when the handle is no longer valid.

pub fn value_ref(self, runtime: &MotionRuntime) -> &T

Borrows the current value.

Panics

Panics when the handle is no longer valid.

pub fn try_value(self, runtime: &MotionRuntime) -> Option<&T>

Borrows the current value when the handle is valid.

pub fn state(self, runtime: &MotionRuntime) -> Option<AnimationState>

Returns the current state when the handle is valid.

pub fn is_active(self, runtime: &MotionRuntime) -> bool

Returns whether the motion is active.

pub fn is_completed(self, runtime: &MotionRuntime) -> bool

Returns whether the motion completed.

pub fn pause(self, runtime: &mut MotionRuntime) -> bool

Pauses the motion if the handle is valid.

pub fn resume(self, runtime: &mut MotionRuntime) -> bool

Resumes the motion if the handle is valid.

pub fn cancel(self, runtime: &mut MotionRuntime) -> bool

Cancels the motion if the handle is valid.

pub fn seek(self, progress: f32, runtime: &mut MotionRuntime) -> bool

Seeks the motion to normalized progress if the handle is valid.

pub fn finish(self, runtime: &mut MotionRuntime) -> bool

Moves the motion to completion if the handle is valid.

pub fn remove(self, runtime: &mut MotionRuntime) -> bool

Removes the motion from the runtime.

Trait Implementations

impl<T> Clone for Motion<T>

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<T> Copy for Motion<T>

impl<T: Debug> Debug for Motion<T>

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

Formats the value using the given formatter.

impl<T: Eq> Eq for Motion<T>

impl<T: Hash> Hash for Motion<T>

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl<T: PartialEq> PartialEq for Motion<T>

fn eq(&self, other: &Motion<T>) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
