Struct ForeignKey 

pub struct ForeignKey {
    pub child_columns: Box<[String]>,
    pub parent_table: String,
    pub parent_columns: Box<[String]>,
    pub on_delete: RefAct,
    pub on_update: RefAct,
    pub deferred: bool,
    pub decl_order: usize,
}

Fields

child_columns: Box<[String]>

Columns in this table (child side). Never empty (validated at parse time).

parent_table: String

Referenced (parent) table

parent_columns: Box<[String]>

Parent-side referenced columns. Empty means “use parent’s PRIMARY KEY”.

on_update: RefAct

deferred: bool

DEFERRABLE INITIALLY DEFERRED

decl_order: usize

Declaration order among this table’s foreign key constraints.
