Struct ValueBatch

Source

pub struct ValueBatch {
    pub n_rows: usize,
    pub n_nodes: usize,
    pub values: Arc<[f64]>,
}

Expand description

Column-major batch of continuous values: values[node * n_rows + row].

Fields§

§n_rows: usize

Number of rows (samples / units).

§n_nodes: usize

Number of nodes (columns).

§values: Arc<[f64]>

Flat column-major storage.
