Struct PerClassSupport 

pub struct PerClassSupport {
    pub n_gt: Vec<u32>,
    pub n_dt: Vec<u32>,
}

Per-category support counts that build_per_class consumes alongside Accumulated. Pre-aggregated on the caller’s side so the table builder is a pure fold; streaming and batch paths produce these counts from different substrates (the cells store vs. the parsed dataset) but both feed into the same builder.

Fields

n_gt: Vec<u32>

Non-ignore GT count, K-axis indexed (matching Accumulated’s K-axis order). n_gt[k] is the count for category k.

n_dt: Vec<u32>

DT count, K-axis indexed. n_dt[k] is the count for category k.

Implementations

impl PerClassSupport

pub fn zeros(n_categories: usize) -> Self

Construct a zero-filled support struct of length n_categories. Useful when the caller is going to fill it in from a cells-store scan.

Trait Implementations

impl Clone for PerClassSupport

fn clone(&self) -> PerClassSupport

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for PerClassSupport

fn fmt(&self, f: &mut Formatter<'_>) -> Result

impl Default for PerClassSupport

fn default() -> PerClassSupport

Returns the “default value” for a type.
