Implementations

impl Identity

pub fn always(name: impl Into<Cow<'static, str>>) -> Self

Creates a GENERATED ALWAYS AS IDENTITY backed by the sequence name.

pub fn by_default(name: impl Into<Cow<'static, str>>) -> Self

Creates a GENERATED BY DEFAULT AS IDENTITY backed by the sequence name.

pub fn schema(self, schema: impl Into<Cow<'static, str>>) -> Self

Sets the sequence’s schema.

impl Identity

pub fn to_sql(&self) -> String

Renders GENERATED ALWAYS AS IDENTITY (or BY DEFAULT), with a leading space and the sequence options in parentheses when any are set. The sequence name and schema are not rendered.
