Enum JoinKeyMode 

pub enum JoinKeyMode {
    Origin,
    Seq,
    OriginSeq,
    Field(String),
}

Join-key extraction mode. Started in Phase D-1 with row- intrinsic-only modes; Phase D-2 adds payload-keyed extraction via JoinKeyMode::Field.

Variants

Origin

Hash on ResultRow.origin (8-byte LE encoding).

Seq

Hash on ResultRow.seq.0 (8-byte LE encoding).

OriginSeq

Hash on the (origin, seq) tuple (16-byte LE encoding).

Field(String)

Hash on the canonical string projection of a row’s payload field at path. JSON payloads only; rows whose path resolves to a missing key, non-JSON payload, or non-scalar leaf are silently dropped from the build side (so unmatched-build outer-join semantics treat them as if the row never existed).

Trait Implementations

impl Clone for JoinKeyMode

fn clone(&self) -> JoinKeyMode

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for JoinKeyMode

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for JoinKeyMode

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for JoinKeyMode

fn eq(&self, other: &JoinKeyMode) -> 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 JoinKeyMode

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for JoinKeyMode

impl StructuralPartialEq for JoinKeyMode
