Generated identity column constraint

Fields

always: bool

True for ALWAYS, False for BY DEFAULT

on_null: bool

ON NULL (only valid with BY DEFAULT)

start: Option<Box<Expression>>

START WITH value

increment: Option<Box<Expression>>

INCREMENT BY value

minvalue: Option<Box<Expression>>

MINVALUE

maxvalue: Option<Box<Expression>>

MAXVALUE

cycle: Option<bool>

CYCLE option - Some(true) = CYCLE, Some(false) = NO CYCLE, None = not specified

Trait Implementations

impl Clone for GeneratedAsIdentity

fn clone(&self) -> GeneratedAsIdentity

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for GeneratedAsIdentity

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for GeneratedAsIdentity

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for GeneratedAsIdentity

fn eq(&self, other: &GeneratedAsIdentity) -> 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 Serialize for GeneratedAsIdentity

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
