Struct BitPackedPath 

pub struct BitPackedPath {
    pub path_bits: u128,
    pub path_length: u8,
    pub prediction: f32,
}

Bit-packed decision path for ultra-compact storage

Fields

path_bits: u128

Packed decision bits (left = 0, right = 1)

path_length: u8

Number of decisions in the path

prediction: f32

Final prediction value

Implementations
