Struct smartnoise_validator::proto::Quantile

pub struct Quantile {
    pub alpha: f64,
    pub interpolation: String,
}

Quantile Component

Get values corresponding to specified quantiles 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 quantile on the arguments.

Arguments

• data - Array - Atomic type must be numeric.
• candidates - Array - Set from which the Exponential mechanism will return an element. Type must match with atomic type of data. This value must be column-conformable with data.

Returns

• Value - Array - Quantile values for each column.

Fields

alpha: f64

Desired quantiles, defined on [0,1]. Examples: 0: min, 0.5: median, 1: max

interpolation: String

Interpolation strategy. One of [lower, upper, midpoint, nearest, linear]

Trait Implementations

impl Clone for Quantile

fn clone(&self) -> Quantile

impl Debug for Quantile

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

Formats the value using the given formatter.

impl Default for Quantile

fn default() -> Quantile

Returns the “default value” for a type.

impl Message for Quantile

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

fn merge_field<B>(
    &mut self,
    tag: u32,

) -> Result<(), DecodeError> where
    B: Buf, 

fn encoded_len(&self) -> usize

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

fn clear(&mut self)

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,
