Enum HistNodeView 

#[non_exhaustive]
pub enum HistNodeView {
    Leaf {
        value: f64,
    },
    Split {
        feature: usize,
        threshold: f64,
        left: usize,
        right: usize,
    },
}

Public view of a HistNode for ONNX export, with bin thresholds converted to raw feature value thresholds.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Leaf

Leaf node.

Fields

value: f64

Prediction value.

Split

Internal split node.

Fields

feature: usize

Feature index.

threshold: f64

Raw feature threshold (≤ goes left).

left: usize

Left child index.

right: usize

Right child index.
