Struct ForeignKey 

pub struct ForeignKey {

    pub referenced_index: Option<[u8; 16]>,
    pub referenced_key: Option<String>,
    pub name: Option<String>,
    pub object_id: Option<[u8; 16]>,

    pub enforced: bool,
    pub validated: bool,
    pub deferrable: bool,
    pub initially_deferred: bool,
    pub period: bool,
}

Table-level foreign key. Compilation preserves an omitted referenced column list as empty; validation fills it from the primary key before publication.

Fields

referenced_index: Option<[u8; 16]>

Incarnation of the selected unique index, retained across index and constraint renames.

referenced_key: Option<String>

Name of the selected unique index in the referenced relation namespace.

name: Option<String>

object_id: Option<[u8; 16]>

Logical foreign-key identity shared by a partition family for enforcement and deferred events.

catalog_identity: Option<ConstraintCatalogIdentity>

Independent catalog row lifetime and OID, preserved through renames and distinct in each partition.

local_columns: Vec<String>

ref_table: String

ref_columns: Vec<String>

on_update: ForeignKeyAction

on_delete: ForeignKeyAction

on_delete_set_columns: Vec<String>

Optional column subset for ON DELETE SET NULL (...) and ON DELETE SET DEFAULT (...). Empty means every local FK column participates.

match_type: ForeignKeyMatch

enforced: bool

validated: bool

deferrable: bool

initially_deferred: bool

period: bool

The final local and referenced columns use PostgreSQL PERIOD coverage.
