Struct RelationshipMapping 

pub struct RelationshipMapping {
    pub relationship_type: String,
    pub source_id_field: String,
    pub target_id_field: String,
    pub type_field: Option<String>,
    pub property_fields: Vec<String>,
    pub filter_conditions: Option<String>,
    pub source_label: Option<String>,
    pub target_label: Option<String>,
}

Configuration for mapping relationship types to dataset fields

Fields

relationship_type: String

The relationship type (e.g., “KNOWS”, “PURCHASED”)

source_id_field: String

Field containing the source node ID

target_id_field: String

Field containing the target node ID

type_field: Option<String>

Optional field containing the relationship type

property_fields: Vec<String>

Optional fields that define relationship properties

filter_conditions: Option<String>

Optional filter conditions for this relationship type

source_label: Option<String>

Node labels at the source and target end, like FROM Post TO Person in a Kuzu REL table. Only needed to plan relationship-type alternation ([:A|B]) or multi-label nodes, where they decide which label goes with which type.

target_label: Option<String>

Implementations

impl RelationshipMapping

pub fn new<S: Into<String>>( rel_type: S, source_field: S, target_field: S, ) -> Self

Create a new relationship mapping

pub fn with_endpoints<S: Into<String>>( self, source_label: S, target_label: S, ) -> Self

Set the node labels this relationship type connects

pub fn with_type_field<S: Into<String>>(self, type_field: S) -> Self

Set the type field for this relationship

pub fn with_properties(self, fields: Vec<String>) -> Self

Add property fields to the mapping

pub fn with_filter<S: Into<String>>(self, filter: S) -> Self

Add filter conditions for this relationship type
