Struct AsinhCodec 

pub struct AsinhCodec {
    pub linear_width: f64,
    pub version: StaticCodecVersion<1, 0, 0>,
}

Asinh codec, which applies a quasi-logarithmic transformation on encoding.

For values close to zero that are within the codec’s linear_width, the transform is close to linear. For values of larger magnitudes, the transform is asymptotically logarithmic. Unlike a logarithmic transform, this codec supports all finite values, including negative values and zero.

In detail, the codec calculates $c = w \cdot \text{asinh}\left( \frac{x}{w} \right)$ on encoding and $d = w \cdot \text{sinh}\left( \frac{c}{w} \right)$ on decoding, where $w$ is the codec’s linear_width.

The codec only supports finite floating point numbers.

Fields

linear_width: f64

The width of the close-to-zero input value range where the transform is nearly linear

version: StaticCodecVersion<1, 0, 0>

The codec’s encoding format version. Do not provide this parameter explicitly.

Trait Implementations

impl Codec for AsinhCodec

type Error = AsinhCodecError

Error type that may be returned during encodeing and decodeing.

Encodes the data and returns the result.

fn decode(&self, encoded: AnyCowArray<'_>) -> Result<AnyArray, Self::Error>

Decodes the encoded data and returns the result.

fn decode_into( &self, encoded: AnyArrayView<'_>, decoded: AnyArrayViewMut<'_>, ) -> Result<(), Self::Error>
