Enum Param 

pub enum Param {
    Value(f64),
    Keys(Vec<Key>),
    Expr(ExprParam),
}

A number, keyframes over the clip’s source time (docs/timeline.md), or an expression over it (st, docs/compositing.md#expressions). An array holding any object is keys, and a key that doesn’t read is an error (never an expression, whose ease is another curve).

Variants

Value(f64)

Keys(Vec<Key>)

Expr(ExprParam)

Implementations

impl Param

pub fn is_constant(&self) -> bool

pub fn at(&self, t: f64) -> f64

The value at source time t (s); held before the first and after the last key.
