Struct Keyframe 

pub struct Keyframe<T: Lerp> {
    pub timestamp: Duration,
    pub value: T,
    pub easing: Easing,
}

A single keyframe in an animation track.

The easing field controls the interpolation from this keyframe to the next one. The last keyframe’s easing is never used (there is no subsequent keyframe to interpolate toward).

Ordering

Keyframes are ordered and compared by timestamp only. Two keyframes at the same timestamp are considered equal regardless of their values or easing — this keeps binary-search by timestamp correct inside AnimationTrack (added in issue #350).

Fields

timestamp: Duration

Position of this keyframe on the timeline.

value: T

Value held at (and interpolated from) this keyframe.

easing: Easing

Easing applied for the transition from this keyframe to the next.

Implementations

impl<T: Lerp> Keyframe<T>

pub fn new(timestamp: Duration, value: T, easing: Easing) -> Self

Creates a new keyframe.

Trait Implementations

impl<T: Clone + Lerp> Clone for Keyframe<T>

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

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<T: Debug + Lerp> Debug for Keyframe<T>

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

Formats the value using the given formatter.

impl<'de, T> Deserialize<'de> for Keyframe<T>

where T: Deserialize<'de> + Lerp,

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<T: Lerp> Eq for Keyframe<T>

impl<T: Lerp> Ord for Keyframe<T>

fn cmp(&self, other: &Self) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl<T: Lerp> PartialEq for Keyframe<T>

fn eq(&self, other: &Self) -> 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.

impl<T: Lerp> PartialOrd for Keyframe<T>

fn partial_cmp(&self, other: &Self) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl<T> Serialize for Keyframe<T>

where T: Serialize + Lerp,

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
