Struct smartnoise_validator::proto::Filter

pub struct Filter {}

Filter Component

Filters data down into only the desired rows.

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 filter on the arguments.

Arguments

• data - Array
• mask - Array - Boolean mask giving whether or not each row should be kept. Example value: data[‘age’] == ‘4’

Returns

• Value - Array - Data with only the desired rows.

Trait Implementations

impl Clone for Filter

fn clone(&self) -> Filter

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Component for Filter

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

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

impl Debug for Filter

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

Formats the value using the given formatter.

impl Default for Filter

fn default() -> Filter

Returns the “default value” for a type.

impl Message for Filter

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

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

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<Filter> for Filter

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