Enum FieldDatabaseDefault 

pub enum FieldDatabaseDefault {
    None,
}

FieldDatabaseDefault

FieldDatabaseDefault declares the database-level default contract for one runtime field. It is intentionally separate from Rust Default so schema reconciliation never treats construction defaults as persisted-row policy.

Variants

None

No database-level default is declared for this field.
