Required Methods

fn table(&self) -> &dyn PostgresTableInfo

fn is_serial(&self) -> bool

fn is_bigserial(&self) -> bool

fn is_generated_identity(&self) -> bool

Provided Methods

fn foreign_key(&self) -> Option<&'static dyn PostgresColumnInfo>

Returns the foreign key reference if this column has one

fn as_postgres_column(&self) -> &dyn PostgresColumnInfo

where Self: Sized,

Erased access to the Postgres column info.

fn foreign_key_core(&self) -> Option<&'static dyn SQLColumnInfo>

Core-erased foreign key reference for call sites that only need generic info.
