pub fn dequant_q5_k(src: &[u8]) -> Result<Vec<f32>, QuantError>Expand description
Dequantize a Q5_K buffer into f32. See the module doc comment and
Q5_K_BLOCK_BYTES for the block layout. Shares Q4_K’s scale/min
packing (q4_k_scale_min) and 4-outer-iteration structure; the only
difference is each nibble gets a 5th bit from qh, whose 32 bytes
are reused across all 4 outer iterations at different bit positions
(u1/u2, doubling by 4 each iteration) rather than being consumed
sequentially the way qs is.
