Trait envelope::Point

pub trait Point<X, Y>: Copy + Clone {
    fn x_to_scalar(x: X) -> Y::Scalar where Y: Spatial;
    fn x(&self) -> X;
    fn y(&self) -> Y;

    fn interpolate(x: X, start: &Self, end: &Self) -> Y where X: PartialEq, Y: PartialEq + Spatial, Y::Scalar: Float { ... }
}

Implement this for types to be used as points on an Envelope.

Required Methods

fn x_to_scalar(x: X) -> Y::Scalar where Y: Spatial

Convert X to Y's Scalar.

fn x(&self) -> X

X (often associated with time).

fn y(&self) -> Y

Y (often associated with some value).

Provided Methods

fn interpolate(x: X, start: &Self, end: &Self) -> Y where X: PartialEq, Y: PartialEq + Spatial, Y::Scalar: Float

Interpolate between two points and return y for the given x.
