Struct CheckConstraint 

pub struct CheckConstraint {
    pub id: u16,
    pub name: String,
    pub expr: CheckExpr,
}

A CHECK constraint: the row is rejected when expr evaluates to False (SQL three-valued logic: Unknown/True both pass).

Fields

id: u16

name: String

expr: CheckExpr

Trait Implementations

impl Clone for CheckConstraint

fn clone(&self) -> CheckConstraint

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CheckConstraint

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for CheckConstraint

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for CheckConstraint

fn eq(&self, other: &CheckConstraint) -> 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 CheckConstraint

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
