Enum StorageFormat 

pub enum StorageFormat {
    Int8Widened,
    NativeInt4,
}

How quantized values are stored on disk inside the ONNX initializer.

ONNX DequantizeLinear accepted only INT8 inputs before opset 21. From opset 21 it also accepts native INT4 (and UINT4), which is 2× smaller on disk.

Variants

Int8Widened

INT4 values widened to INT8 bytes. Compatible with opset 10+ — the default for backward compatibility, but gives only 4× compression.

NativeInt4

Native DataType::Int4 with two values packed per byte. Requires opset 21. Gives the full 8× compression for INT4 models.

Trait Implementations

impl Clone for StorageFormat

fn clone(&self) -> StorageFormat

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for StorageFormat

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

Formats the value using the given formatter.

impl PartialEq for StorageFormat

fn eq(&self, other: &StorageFormat) -> 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.
