Struct smartnoise_runtime::proto::Union

pub struct Union {
    pub flatten: bool,
}

Union Component

Union the arrays in the arguments into one array.

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 union on the arguments.

Returns

• Value - Array - Array (or indexmap of arrays) containing item(s) representing the concatenation of all partitions

Fields

flatten: bool

When set, the output is an array. When unset, the output is an indexmap of arrays.

Trait Implementations

impl Clone for Union

pub fn clone(&self) -> Union

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Component for Union

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 Union

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

Formats the value using the given formatter.

impl Default for Union

pub fn default() -> Union

Returns the “default value” for a type.

impl Evaluable for Union

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

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

impl Message for Union

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<Union> for Union

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

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

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

This method tests for !=.

impl Sensitivity for Union

pub fn compute_sensitivity(
    &self,
    privacy_definition: &PrivacyDefinition,
    properties: &IndexMap<IndexKey, ValueProperties, RandomState>,
    sensitivity_type: &SensitivitySpace
) -> Result<Value, Error>

Derivation for the sensitivity of an aggregator based on available local metadata.
