Struct Scaler 

pub struct Scaler {
    pub shift_value: Vec<f64>,
    pub scale_value: Vec<f64>,
}

A scaling operation.

This function has the following formula:

.. math:: f(x) = scaleValue \cdot (x + shiftValue)

If the scaleValue is not given, the default value 1 is used. If the shiftValue is not given, the default value 0 is used.

If scaleValue and shiftValue are each a single value and the input is an array, then the scale and shift are applied to each element of the array.

If the input is an integer, then it is converted to a double to perform the scaling operation. If the output type is an integer, then it is cast to an integer. If that cast is lossy, then an error is generated.

Fields

shift_value: Vec<f64>

scale_value: Vec<f64>

Trait Implementations

impl Clone for Scaler

fn clone(&self) -> Scaler

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Scaler

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

Formats the value using the given formatter.

impl Default for Scaler

fn default() -> Self

Returns the “default value” for a type.

impl Message for Scaler

fn encoded_len(&self) -> usize

Returns the encoded length of the message without a length delimiter.

fn clear(&mut self)

Clears the message, resetting all fields to their default.

fn encode(&self, buf: &mut impl BufMut) -> Result<(), EncodeError>

where Self: Sized,

Encodes the message to a buffer.

fn encode_to_vec(&self) -> Vec<u8>

where Self: Sized,

Encodes the message to a newly allocated buffer.

fn encode_length_delimited( &self, buf: &mut impl BufMut, ) -> Result<(), EncodeError>

where Self: Sized,

Encodes the message with a length-delimiter to a buffer.

fn encode_length_delimited_to_vec(&self) -> Vec<u8>

where Self: Sized,

Encodes the message with a length-delimiter to a newly allocated buffer.

fn decode(buf: impl Buf) -> Result<Self, DecodeError>

where Self: Default,

Decodes an instance of the message from a buffer.

fn decode_length_delimited(buf: impl Buf) -> Result<Self, DecodeError>

where Self: Default,

Decodes a length-delimited instance of the message from the buffer.

fn merge(&mut self, buf: impl Buf) -> Result<(), DecodeError>

where Self: Sized,

Decodes an instance of the message from a buffer, and merges it into self.

fn merge_length_delimited(&mut self, buf: impl Buf) -> Result<(), DecodeError>

where Self: Sized,

Decodes a length-delimited instance of the message from buffer, and merges it into self.

impl PartialEq for Scaler

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