Struct FixedOffsetScaleCodec

pub struct FixedOffsetScaleCodec {
    pub offset: f64,
    pub scale: f64,
}

Fixed offset-scale codec which calculates c = (x-o) / s on encoding and d = (c*s) + o on decoding.

• Setting o = mean(x) and s = std(x) normalizes that data.
• Setting o = min(x) and s = max(x) - min(x) standardizes the data.

The codec only supports floating point numbers.

Fields

offset: f64

The offset of the data.

scale: f64

The scale of the data.

Trait Implementations

impl Clone for FixedOffsetScaleCodec

fn clone(&self) -> FixedOffsetScaleCodec

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Codec for FixedOffsetScaleCodec

type Error = FixedOffsetScaleCodecError

Error type that may be returned during encodeing and decodeing.

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

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>

Decodes the encoded data and writes the result into the provided decoded output.

impl<'de> Deserialize<'de> for FixedOffsetScaleCodec

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl JsonSchema for FixedOffsetScaleCodec

fn schema_name() -> Cow<'static, str>

The name of the generated JSON Schema.

fn schema_id() -> Cow<'static, str>

Returns a string that uniquely identifies the schema produced by this type.

fn json_schema(generator: &mut SchemaGenerator) -> Schema

Generates a JSON Schema for this type.

fn always_inline_schema() -> bool

Whether JSON Schemas generated for this type should be included directly in parent schemas, rather than being re-used where possible using the $ref keyword.

impl Serialize for FixedOffsetScaleCodec

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl StaticCodec for FixedOffsetScaleCodec

const CODEC_ID: &'static str = "fixed-offset-scale"

Codec identifier.

type Config<'de> = FixedOffsetScaleCodec

Configuration type, from which the codec can be created infallibly.

fn from_config(config: Self::Config<'_>) -> Self

Instantiate a codec from its configuration.

fn get_config(&self) -> StaticCodecConfig<'_, Self>

Get the configuration for this codec.
