Struct Q4Block 

pub struct Q4Block {
    pub scale: f16,
    pub data: [u8; 16],
}

A block of Q4_0 quantized data.

Fields

scale: f16

Scale factor (stored as f16).

data: [u8; 16]

Packed quantized values (16 bytes = 32 x 4-bit).

Implementations

impl Q4Block

pub fn new(scale: f16, data: [u8; 16]) -> Self

Creates a new Q4 block.

pub fn unpack(&self) -> [i8; 32]

Extracts the 4-bit values as i8 (range -8 to 7).

pub fn pack(values: &[i8; 32]) -> [u8; 16]

Packs 32 i8 values (-8 to 7 range) into 16 bytes.

pub fn to_bytes(&self) -> Vec<u8>

Returns the byte representation of this block.

pub fn from_bytes(bytes: &[u8]) -> Option<Self>

Creates a block from bytes.
