Struct RelationEdge 

pub struct RelationEdge { /* private fields */ }

RelationEdge

Schema-side relation edge declaration over one or more local component fields. Runtime acceptance still owns durable field IDs and slots; this helper proves arity/order/kind compatibility before a tuple relation shape can be admitted.

Implementations

impl RelationEdge

pub const fn new( ident: &'static str, target: &'static str, local_fields: &'static [&'static str], ) -> Self

Build one relation-edge declaration from a relation name, target entity path, and ordered local component fields.

pub const fn ident(&self) -> &'static str

Borrow the relation-edge name used by diagnostics.

pub const fn target(&self) -> &'static str

Borrow the target entity path.

pub const fn local_fields(&self) -> &'static [&'static str]

Borrow ordered local source fields that map to the target primary key.

pub fn validate_for_source(&self, source: &Entity) -> Result<(), ErrorTree>

Validate this edge against one source entity and the target entity stored in the current schema graph.

pub fn validate_against_entities( &self, source: &Entity, target: &Entity, ) -> Result<(), ErrorTree>

Validate this edge against explicit source and target entity metadata.
