SaveOptions

quantize_rs::onnx_utils::graph_builder

Struct SaveOptions 

Source 
pub struct SaveOptions {
    pub native_int4: bool,
}
Expand description

Options controlling how a quantized model is written to disk.

Fields§

§native_int4: bool

Use native ONNX INT4 storage (opset 21, DataType::Int4) instead of widening INT4 values into INT8 bytes.

Native storage halves the on-disk size of INT4-quantized weights (true 8× compression from FP32) but raises the required opset to 21. Older runtimes without opset 21 support will refuse to load the model. Defaults to false for backward compatibility.

Only affects weights where QdqWeightInput::bits is 4; INT8 weights are stored as INT8 regardless of this flag.

Implementations§

Source§

impl SaveOptions

Source

pub fn with_native_int4(self, enabled: bool) -> Self
