Struct Imputer 

pub struct Imputer {
    pub imputed_value: Option<ImputedValue>,
    pub replace_value: Option<ReplaceValue>,
}

A transformer that replaces missing values with a default value, such as a statistically-derived value.

If ReplaceValue is set, then missing values of that type are replaced with the corresponding value.

For example: if replaceDoubleValue is set to NaN and a single NaN double value is provided as input, then it is replaced by imputedDoubleValue. However if the input is an array of doubles, then any instances of NaN in the array is replaced with the corresponding value in imputedDoubleArray.

Fields

imputed_value: Option<ImputedValue>

replace_value: Option<ReplaceValue>

Trait Implementations

impl Clone for Imputer

fn clone(&self) -> Imputer

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Imputer

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

Formats the value using the given formatter.

impl Default for Imputer

fn default() -> Self

Returns the “default value” for a type.

impl Message for Imputer

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 Imputer

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