Enum TimingFunction 

pub enum TimingFunction {
    Linear,
    CubicBezier(f32, f32, f32, f32),
    Steps(u32, bool),
}

イージング関数。CSS の transition-timing-function / animation-timing-function。

Variants

Linear

CubicBezier(f32, f32, f32, f32)

3次ベジェ制御点 (x1, y1, x2, y2)。ease/ease-in/out/in-out もこれで表現。

Steps(u32, bool)

steps(n, jump-start|jump-end)。bool=jump_start。

Implementations

impl TimingFunction

pub fn parse(s: &str) -> TimingFunction

CSS のキーワード/関数表記をパース。

pub fn ease(&self, t: f32) -> f32

線形進捗 t(0..=1) をイージング後の進捗に変換する。

Trait Implementations

impl Clone for TimingFunction

fn clone(&self) -> TimingFunction

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TimingFunction

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

Formats the value using the given formatter.

impl PartialEq for TimingFunction

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