Struct TableConstraintDef 

pub struct TableConstraintDef<X: Extension = NoExt> {
    pub name: Option<Ident>,
    pub constraint: TableConstraint<X>,
    pub no_inherit: bool,
    pub not_valid: bool,
    pub characteristics: Option<Box<ConstraintCharacteristics>>,
    pub meta: Meta,
}

An SQL table constraint def.

Fields

name: Option<Ident>

Name referenced by this syntax.

constraint: TableConstraint<X>

The constraint kind and its data; see TableConstraint.

no_inherit: bool

The NO INHERIT marker (PostgreSQL/DuckDB): the constraint is not inherited by child tables. It rides PostgreSQL’s shared ConstraintAttributeSpec slot alongside characteristics, order-free with NOT VALID and DEFERRABLE. PostgreSQL admits it only on CHECK constraints (FOREIGN KEY / PRIMARY KEY / UNIQUE / EXCLUDE reject it in the grammar action — reproduced at parse), so a set flag always pairs with a TableConstraint::Check. Gated for acceptance by ConstraintSyntax::constraint_no_inherit_not_valid.

not_valid: bool

The NOT VALID marker (PostgreSQL/DuckDB): the constraint is recorded but existing rows are not checked. Shares the ConstraintAttributeSpec slot with no_inherit and characteristics. PostgreSQL admits it only on CHECK and FOREIGN KEY constraints (PRIMARY KEY / UNIQUE / EXCLUDE reject it — reproduced at parse), and there is no column-level form. Gated for acceptance by the same ConstraintSyntax::constraint_no_inherit_not_valid flag as no_inherit.

characteristics: Option<Box<ConstraintCharacteristics>>

The trailing DEFERRABLE/INITIALLY characteristics, when written; boxed as the cold clause it is (see ColumnConstraint::characteristics).

meta: Meta

Source location and node identity.

Trait Implementations

impl<X: Clone + Extension> Clone for TableConstraintDef<X>

fn clone(&self) -> TableConstraintDef<X>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<X: Debug + Extension> Debug for TableConstraintDef<X>

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

Formats the value using the given formatter.

impl<'de, X> Deserialize<'de> for TableConstraintDef<X>

where X: Deserialize<'de> + Extension,

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<X: Eq + Extension> Eq for TableConstraintDef<X>

impl<X: Hash + Extension> Hash for TableConstraintDef<X>

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)
