Implementations

impl Identity

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

Create a new identity with GENERATED ALWAYS AS IDENTITY

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

Create a new identity with GENERATED BY DEFAULT AS IDENTITY

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

Set schema

impl Identity

pub fn to_sql(&self) -> String

Generate the GENERATED AS IDENTITY clause

Trait Implementations

impl Clone for Identity

fn clone(&self) -> Identity

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Identity

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for Identity

fn eq(&self, other: &Identity) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Eq for Identity

impl StructuralPartialEq for Identity
