Struct smartnoise_runtime::proto::Partition

pub struct Partition {}

Partition Component

Split the rows of data into either k equally sized partitions, or by the categories of a vector

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 partition on the arguments.

Arguments

• data - Array - Must be a dataframe or an array
• num_partitions - Array
• by - Array

Returns

• Value - Indexmap

Trait Implementations

impl Clone for Partition

pub fn clone(&self) -> Partition

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Component for Partition

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 Partition

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

Formats the value using the given formatter.

impl Default for Partition

pub fn default() -> Partition

Returns the “default value” for a type.

impl Evaluable for Partition

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

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

impl Expandable for Partition

pub fn expand_component(
    &self,
    _privacy_definition: &Option<PrivacyDefinition>,
    component: &Component,
    _public_arguments: &IndexMap<IndexKey, &Value, RandomState>,
    properties: &IndexMap<IndexKey, ValueProperties, RandomState>,
    component_id: u32,
    maximum_id: u32
) -> Result<ComponentExpansion, Error>

Concrete implementation for an Expandable component that returns a patch that may be applied to a computation graph.

impl Message for Partition

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<Partition> for Partition

pub fn eq(&self, other: &Partition) -> 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 !=.
