Trait Quantization

pub trait Quantization<E>
where
    E: Float + Send + Sync,
{
    // Required methods
    fn range(&self) -> (E, E);
    fn quantize<Q>(&self, values: &[E]) -> Vec<Q>
       where Q: PrimInt;
    fn quantize_one<Q>(&self, value: E) -> Q
       where Q: PrimInt;
    fn dequantize<Q>(&self, values: &[Q]) -> Vec<E>
       where Q: PrimInt;
    fn dequantize_one<Q>(&self, value: Q) -> E
       where Q: PrimInt;
}

Quantization scheme to convert elements of a higher precision data type E to a lower precision data type Q and vice-versa.

Required Methods

fn range(&self) -> (E, E)

Returns the quantization range [a, b].

fn quantize<Q>(&self, values: &[E]) -> Vec<Q>

where Q: PrimInt,

Convert the values to a lower precision data type.

fn quantize_one<Q>(&self, value: E) -> Q

where Q: PrimInt,

Convert a single value to a lower precision data type.

fn dequantize<Q>(&self, values: &[Q]) -> Vec<E>

where Q: PrimInt,

Convert the values back to a higher precision data type.

fn dequantize_one<Q>(&self, value: Q) -> E

where Q: PrimInt,

Convert a single value back to a higher precision data type.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
