Trait envelope::Point

pub trait Point: Clone {
    type X: PartialEq + Clone;
    type Y: PartialEq + Spatial;
    fn x_to_scalar(x: Self::X) -> <Self::Y as Spatial>::Scalar;
    fn x(&self) -> Self::X;
    fn y(&self) -> Self::Y;

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

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

Associated Types

type X: PartialEq + Clone

type Y: PartialEq + Spatial

Required Methods

fn x_to_scalar(x: Self::X) -> <Self::Y as Spatial>::Scalar

Convert X to Y's Scalar.

fn x(&self) -> Self::X

X (often associated with time).

fn y(&self) -> Self::Y

Y (often associated with some value).

Provided Methods

fn interpolate(x: Self::X, start: &Self, end: &Self) -> Self::Y where
    <Self::Y as Spatial>::Scalar: Scalar, 

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