Module ffi 

FFI bindings to the C kernels in c-kernels/.

These wrappers provide safe Rust interfaces to the compiled C implementations of the hot numerical loops. The Rust side handles all validation; the C code only performs the tight inner loops.

Functions

c_compressed_attention_logits

Compute compressed attention logits via C kernel.

c_decode_vector_block

Decode a vector block: gather codewords by index.

c_encode_vector_block

Encode a vector block: find nearest codeword for each block of block_dim floats. Returns the codeword indices.

c_softmax

Numerically stable softmax via C kernel.
