Fields

field_path: Vec<PathSeg>

Path of the ID field inside key/value (“k”/“v” prefix in field_in).

brand: String

on_missing: OnMissing

validated: bool

false — graph-only edge; validator reports it as UnvalidatedEdge unless an explicit fk declaration covers it.

Index

to is a secondary index of from.

Denorm

to is a denormalization of from.

Counter

Field field in from is recomputed from to.

Trait Implementations

impl Clone for RelationKind

fn clone(&self) -> RelationKind

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RelationKind

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

Formats the value using the given formatter.

impl Eq for RelationKind

impl PartialEq for RelationKind

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
