Struct InheritedDefinitions 

pub struct InheritedDefinitions {
    pub expressions: Vec<String>,
    pub not_nulls: Vec<InheritedNotNull>,
    pub keys: usize,
    pub foreign_keys: usize,
    pub unique_indexes: Vec<Vec<IndexKey>>,
}

What a new table takes from its parents before its own definitions: the columns whose expressions the parents give, and the keys and foreign keys a partition clones from its parent.

Fields

expressions: Vec<String>

The columns whose default or generation expression a parent gives and the statement does not replace, which heap_create_with_catalog stores with the relation.

not_nulls: Vec<InheritedNotNull>

The NOT NULL constraints the parents give, in parent order, which AddRelationNotNullConstraints creates after the declared ones.

keys: usize

The parent’s keys, which precede the declared keys of the table.

foreign_keys: usize

The parent’s foreign keys, which precede the declared foreign keys of the table.

unique_indexes: Vec<Vec<IndexKey>>

The key attributes of the parent’s unique indexes that no key constraint owns.
