Enum Angle 

pub enum Angle {
    Constant(f64),
    Parameter {
        index: usize,
        scale: f64,
        offset: f64,
    },
    Input {
        index: usize,
        scale: f64,
        offset: f64,
    },
}

An affine angle expression. References may be shared across gate occurrences.

Variants

Constant(f64)

Constant angle in radians.

Parameter

scale * parameters[index] + offset.

Fields

index: usize

Parameter-vector index.

scale: f64

Chain-rule scale.

offset: f64

Constant phase offset.

Input

scale * inputs[batch, index] + offset.

Fields

index: usize

Input-feature index.

scale: f64

Feature scale.

offset: f64

Constant phase offset.
