Enum WeightFormat 

pub enum WeightFormat {
    Nvfp4,
    Fp8BlockScaled,
    Bf16Dense,
}

2026-09-25: On-disk weight format, derived from detect_nvfp4_variant.

Variants

Nvfp4

2026-09-25: ModelOpt (Standard) or compressed-tensors NVFP4 on disk, and Bf16Raw checkpoints, which the loader quantises to NVFP4.

Fp8BlockScaled

2026-09-25: Block-scaled FP8 E4M3 on disk (Fp8Dequanted).

Bf16Dense

2026-09-25: BF16 on disk. WeightFormat::detect never returns it.

Implementations

impl WeightFormat

pub fn detect(store: &WeightStore, config: &ModelConfig) -> Self

2026-09-25: Detect the weight format from a WeightStore by probing tensor names.

pub fn is_fp8(&self) -> bool

Trait Implementations

impl Clone for WeightFormat

fn clone(&self) -> WeightFormat

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for WeightFormat

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for WeightFormat

fn eq(&self, other: &WeightFormat) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
