Struct TreeNode 

pub struct TreeNode {
    pub value: NodeInfos,
    pub index: usize,
    pub left: usize,
    pub right: usize,
}

A node of a Tree arena. Child indices of 0 mean “no child”.

Fields

value: NodeInfos

What the node tests or predicts.

index: usize

The node’s own index in the arena.

left: usize

Arena index of the left child (x[feature] <= split).

right: usize

Arena index of the right child.

Implementations
