Struct SortKey 

pub struct SortKey {
    pub column: String,
    pub ascending: bool,
}

One post-aggregation sort key of a ShuffleAggregateConsumeRequest’s sort_keys list: a column name plus its sort direction. A named struct (rather than a (String, bool) tuple) so rkyv can derive its codec, mirroring how JoinKeyPair wraps an on tuple.

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

Fields

column: String

Sort column name.

ascending: bool

true = ascending, false = descending.

Trait Implementations

impl Archive for SortKey

where String: Archive, bool: 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 = ArchivedSortKey

The archived representation of this type.

type Resolver = SortKeyResolver

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 SortKey

fn clone(&self) -> SortKey

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SortKey

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

Formats the value using the given formatter.

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

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

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

Deserializes using the given deserializer

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

where String: Serialize<__S>, bool: 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.
