Struct Codebook 

pub struct Codebook {
    pub c_name: &'static str,
    pub values: &'static [f32; 16],
}

The 16-entry value table a codebook format’s 4-bit code indexes.

One slice serves both halves of the kernel: kernel_src formats Self::values into the emitted __constant__ array, and the Rust dequant_twin beside it indexes the same values. There is no second copy of the numbers to drift, which matters more here than for an affine format – a codebook is 16 arbitrary constants that no arithmetic can re-derive, so a single transposed pair would decode every tensor slightly wrong and nothing would look obviously broken.

Fields

c_name: &'static str

The __constant__ array’s identifier in the emitted CUDA C. Must be what dequant_src spells.

values: &'static [f32; 16]

The values, code 0 first.
