Struct FeatureGroup 

pub struct FeatureGroup {
    pub features: Vec<usize>,
    pub row_stride: u32,
    pub hist_offset: u32,
    pub total_bins: u32,
    pub data: Vec<u8>,
}

Fields

features: Vec<usize>

Indices into BinnedDataset::features, in column order.

row_stride: u32

Bytes per row: the feature count rounded up to a multiple of 4, padding bytes zero.

hist_offset: u32

Index of the group’s first bin in the flat histogram; a group’s bins are contiguous there.

total_bins: u32

data: Vec<u8>

Row-major bins: data[row * row_stride + column].
