Struct smartnoise_runtime::proto::Digitize

pub struct Digitize {}

Digitize Component

Maps data to bins.

Bins will be of the form [lower, upper) or (lower, upper]. The null value is the final category.

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 digitize on the arguments.

Arguments

• data - Array - Data to be binned.
• edges - Jagged - Values representing the edges of bins. Edges must be sorted, and may not contain duplicates.
• null_value - Array - Value to which to map if there is no valid bin (e.g. if the element falls outside the bin range). The null value is the final category.
• inclusive_left - Array - Whether or not the left edge of the bin is inclusive, i.e. the bins are of the form [lower, upper).

Returns

• Value - Array

Trait Implementations

impl Clone for Digitize

pub fn clone(&self) -> Digitize

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Component for Digitize

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

impl Debug for Digitize

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

Formats the value using the given formatter.

impl Default for Digitize

pub fn default() -> Digitize

Returns the “default value” for a type.

    properties: &IndexMap<IndexKey, ValueProperties, RandomState>,
    component_id: u32,
    maximum_id: u32
) -> Result<ComponentExpansion, Error>

    &mut self,
    tag: u32,

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,

impl PartialEq<Digitize> for Digitize

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

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

#[must_use]pub fn ne(&self, other: &Rhs) -> bool

This method tests for !=.
