Struct TreeNode 

Source 
#[repr(C)]
pub struct TreeNode {
    pub threshold: u64,
    pub left: u32,
    pub right: u32,
    pub feature: u8,
    pub pad: [u8; 7],
}
Expand description

One tree node, the byte-for-byte mirror of struct mlfq_tree_node.

For an internal node (right != 0), threshold is the split point in nsecs, left/right the child indices and feature the split feature id (0..7). For a leaf (right == 0), left carries the prediction in nsecs. pad is the 7 reserved bytes of the 24-byte node; it is always zeroed so the published node bytes are deterministic.

Fields§

§threshold: u64

Split point in nsecs (internal nodes); 0 on leaves.

§left: u32

Left child index, or the leaf prediction when right == 0.

§right: u32

Right child index; 0 marks a leaf.

§feature: u8

Split feature id (0..7); 0 on leaves.

§pad: [u8; 7]

Reserved padding, always zeroed.
