Enum DiffNode 

pub enum DiffNode {
    Leaf {
        axis: u8,
        minuend: usize,
        subtrahend: usize,
    },
    Neg(NodeId),
    Add(NodeId, NodeId),
    Sub(NodeId, NodeId),
    Mul(NodeId, NodeId),
}

One node of a DiffGraph.

Variants

Leaf

The difference minuend.axis - subtrahend.axis of one coordinate of two different points, given as parameter indices.

Fields

axis: u8

Coordinate: 0, 1 and 2 are x, y and z.

minuend: usize

Index of the parameter whose coordinate is subtracted from.

subtrahend: usize

Index of the parameter whose coordinate is subtracted.

Neg(NodeId)

Negation of a node, with the degree of its operand.

Add(NodeId, NodeId)

Sum of two nodes of the same degree.

Sub(NodeId, NodeId)

Difference of two nodes of the same degree.

Mul(NodeId, NodeId)

Product of two nodes.
