Struct JoinKeyPair 

pub struct JoinKeyPair {
    pub left: String,
    pub right: String,
}

One (left_key, right_key) equi-join pair of a ShuffleConsumeRequest’s on list. The part-owner reconstructs the borrowed join spec from these.

Cross-version safety: new optional fields should be added as Option<T>.

Fields

left: String

Probe-side (left) join field name.

right: String

Build-side (right) join field name.

Trait Implementations

impl Archive for JoinKeyPair

where String: Archive,

const COPY_OPTIMIZATION: CopyOptimization<Self>

An optimization flag that allows the bytes of this type to be copied directly to a writer instead of calling serialize.

type Archived = ArchivedJoinKeyPair

The archived representation of this type.

type Resolver = JoinKeyPairResolver

The resolver for this type. It must contain all the additional information from serializing needed to make the archived type from the normal type.

fn resolve(&self, resolver: Self::Resolver, out: Place<Self::Archived>)

Creates the archived version of this value at the given position and writes it to the given output.

impl Clone for JoinKeyPair

fn clone(&self) -> JoinKeyPair

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for JoinKeyPair

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

Formats the value using the given formatter.

impl<__D: Fallible + ?Sized> Deserialize<JoinKeyPair, __D> for Archived<JoinKeyPair>

where String: Archive, <String as Archive>::Archived: Deserialize<String, __D>,

fn deserialize( &self, deserializer: &mut __D, ) -> Result<JoinKeyPair, <__D as Fallible>::Error>

Deserializes using the given deserializer

impl<__S: Fallible + ?Sized> Serialize<__S> for JoinKeyPair

where String: Serialize<__S>,

fn serialize( &self, serializer: &mut __S, ) -> Result<<Self as Archive>::Resolver, <__S as Fallible>::Error>

Writes the dependencies for the object and returns a resolver that can create the archived type.
