Struct smartnoise_runtime::proto::Variance

pub struct Variance {
    pub finite_sample_correction: bool,
}

Variance Component

Calculates the sample variance for each column of the data.

This struct represents an abstract computation. Arguments are provided via the graph. Additional options are set via the fields on this struct. The return is the result of the variance on the arguments.

Arguments

• data - Array

Returns

• Value - Array - Sample variance for each column of the data.

Fields

finite_sample_correction: bool

Whether or not to use the finite sample correction (Bessel’s correction) to correct the bias in the estimation of the population variance.

Trait Implementations

impl Clone for Variance

pub fn clone(&self) -> Variance

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Component for Variance

pub fn propagate_property(
    &self,
    _privacy_definition: &Option<PrivacyDefinition>,
    _public_arguments: IndexMap<IndexKey, &Value, RandomState>,
    properties: IndexMap<IndexKey, ValueProperties, RandomState>,
    node_id: u32
) -> Result<Warnable<ValueProperties>, Error>

Given properties known about private arguments, and public arguments, derive properties about the resulting data.

impl Debug for Variance

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

Formats the value using the given formatter.

impl Default for Variance

pub fn default() -> Variance

Returns the “default value” for a type.

impl Evaluable for Variance

fn evaluate(
    &self,
    _privacy_definition: &Option<PrivacyDefinition>,
    arguments: NodeArguments
) -> Result<ReleaseNode>

The concrete implementation of the abstract computation that the struct represents.

impl Message for Variance

pub fn encode_raw<B>(&self, buf: &mut B) where
    B: BufMut, 

pub fn merge_field<B>(
    &mut self,
    tag: u32,
    wire_type: WireType,
    buf: &mut B,
    ctx: DecodeContext
) -> Result<(), DecodeError> where
    B: Buf, 

pub fn encoded_len(&self) -> usize

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

pub fn clear(&mut self)

Clears the message, resetting all fields to their default.

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

Encodes the message to a buffer.

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

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

pub fn decode<B>(buf: B) -> Result<Self, DecodeError> where
    Self: Default,
    B: Buf, 

Decodes an instance of the message from a buffer.

pub fn decode_length_delimited<B>(buf: B) -> Result<Self, DecodeError> where
    Self: Default,
    B: Buf, 

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

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

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

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

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

impl PartialEq<Variance> for Variance

pub fn eq(&self, other: &Variance) -> bool

This method tests for self and other values to be equal, and is used by ==.

pub fn ne(&self, other: &Variance) -> bool

This method tests for !=.

impl Sensitivity for Variance

pub fn compute_sensitivity(
    &self,
    privacy_definition: &PrivacyDefinition,
    properties: &IndexMap<IndexKey, ValueProperties, RandomState>,
    sensitivity_type: &SensitivitySpace
) -> Result<Value, Error>
