Struct smartnoise_validator::proto::Cast

pub struct Cast {
    pub atomic_type: String,
}

Cast Component

Cast data to an atomic type.

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 cast on the arguments.

Arguments

• data - Array - Data to be cast to another type.
• true_label - Array - Positive class (class to be mapped to true) for each column. Used only if casting to bool.
• lower - Array - Minimum allowable imputation value. Used only if casting to i64.
• upper - Array - Maximum allowable imputation value. Used only if casting to i64.

Returns

• Value - Array

Fields

atomic_type: String

Type to which data should be cast. One of [string, int, bool, float]

Trait Implementations

impl Clone for Cast

fn clone(&self) -> Cast

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Component for Cast

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 Cast

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

Formats the value using the given formatter.

impl Default for Cast

fn default() -> Cast

Returns the “default value” for a type.

impl Message for Cast

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<Cast> for Cast

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

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

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

This method tests for !=.
