Enum JoinBuildSide 

pub enum JoinBuildSide {
    PreferLeft,
    ForceLeft,
    PreferRight,
    ForceRight,
}

Parameters for which side to use as the build side in a join. Currently only respected by the streaming engine.

Variants

PreferLeft

Unless there’s a very good reason to believe that the right side is smaller, use the left side.

ForceLeft

Regardless of other heuristics, use the left side as build side.

PreferRight

ForceRight

Trait Implementations

impl Clone for JoinBuildSide

fn clone(&self) -> JoinBuildSide

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for JoinBuildSide

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for JoinBuildSide

fn deserialize<__D>( __deserializer: __D, ) -> Result<JoinBuildSide, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Hash for JoinBuildSide

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for JoinBuildSide

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for JoinBuildSide

fn serialize<__S>( &self, __serializer: __S, ) -> Result<<__S as Serializer>::Ok, <__S as Serializer>::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
