Enum IntDtype 

pub enum IntDtype {
    Int8,
    Int4,
}

Supported signed-integer quantization widths.

Variants

Int8

8-bit signed integer quantization.

Int4

4-bit signed integer quantization.

Implementations

impl IntDtype

pub fn bits(self) -> u32

Number of bits in the integer code.

pub fn from_bits(bits: u32) -> Result<Self, GpuOptimError>

Construct an IntDtype from a bit-width, rejecting unsupported widths.

Errors

Returns GpuOptimError::UnsupportedOperation for any width other than 4 or 8.

pub fn q_range(self, scheme: QuantScheme) -> (i32, i32)

Integer clamp range [qmin, qmax] for this width under the given scheme.

Symmetric uses the restricted range (drops the most-negative code) so the grid is symmetric about zero; affine uses the full two’s-complement range.
