Enum WeightFormat 

pub enum WeightFormat {
    Safetensors {
        dir: PathBuf,
    },
    Gguf {
        path: PathBuf,
    },
}

Resolved weight format + path. Produced by WeightFormat::detect from a user-supplied path (HF cache snapshot, local dir, or a .gguf file).

Variants

Safetensors

HuggingFace safetensors directory: config.json + one or more .safetensors shards. The on-disk weights may be plain FP16/BF16 or GPTQ-Int4 (<name>.qweight tensors); this is decided per-tensor by NativeSafetensorsLoader::load_linear.

Fields

dir: PathBuf

Gguf

GGUF single-file format (Llama-family / Qwen3-MoE quantized). Loaded by ferrum_quantization::gguf::GgufLoader.

Fields

path: PathBuf

Implementations

impl WeightFormat

pub fn detect(path: &Path) -> Result<Self>

Detect the weight format from a user-supplied path.

• If path is a file ending in .gguf (case-insensitive) → WeightFormat::Gguf.
• If path is a directory containing config.json → WeightFormat::Safetensors.
• Anything else returns a model error.

pub fn path(&self) -> &Path

The on-disk path this format resolved to.

pub fn label(&self) -> &'static str

Short label for logs / telemetry.

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.
