Enum Keyed 

pub enum Keyed<T> {
    Const(T),
    Keys(Vec<Key<T>>),
    Track(Track<T>),
}

A parameter: a constant, keys sorted by time, or an expression track.

Variants

Const(T)

Keys(Vec<Key<T>>)

Track(Track<T>)

An expression, or keys under one ({"keys", "expr"}).

Implementations

impl<T: Animatable> Keyed<T>

pub fn parse(v: &Value, what: &'static str) -> Result<Self>

A constant, the keyframe form or an expression; what names the parameter in errors.

pub fn from_keys(keys: Vec<Key<T>>) -> Self

Keys in any order (sorted here, stable for equal times).

pub fn is_animated(&self) -> bool

pub fn eval(&self, t: f64) -> Option<T>

The value at source time t (seconds); None for no keys, or an expression that isn’t finite there.

pub fn try_eval(&self, t: f64) -> Result<Option<T>>

Keyed::eval, with an expression’s error.
