}

Identifies any IR object uniquely within a Catalog.

Schema carries an Identifier (schemas are not schema-qualified). All other variants carry QualifiedName. Constraint is identified by (table, name) because constraint names are scoped to their table.

Variants

Schema(Identifier)

A schema (namespace).

Table(QualifiedName)

A table.

Index(QualifiedName)

An index.

Sequence(QualifiedName)

A sequence.

Constraint

A constraint identified by its owning table and constraint name.

Fields

table: QualifiedName

Owning table.

name: Identifier

Constraint name (the name half of the constraint’s qname).

View(QualifiedName)

A view (CREATE VIEW).

Mv(QualifiedName)

A materialized view (CREATE MATERIALIZED VIEW).

Type(QualifiedName)

A user-defined type (enum, domain, or composite).

Function(QualifiedName, NormalizedArgTypes)

A user-defined function — disambiguated by argument types (Decision 7).

Procedure(QualifiedName)

A user-defined procedure — identified by qname only (Decision 2).

Extension(Identifier)

An installed extension.

Trigger(QualifiedName)

A trigger (qname unique within schema).

Publication(Identifier)

A publication (not schema-qualified — publications are a per-database global namespace).

Subscription(Identifier)

A subscription (not schema-qualified — subscriptions are a per-database global namespace, like publications).

EventTrigger(Identifier)

A database-global event trigger.

Statistic(QualifiedName)

A statistics object (CREATE STATISTICS schema.name).

Collation(QualifiedName)

A user-defined collation (CREATE COLLATION schema.name).

The variant lands in v0.3.8 so ordering::change_node can route collation changes correctly; the actual graph edges (column / domain / range / composite-attribute → collation) are added in a follow-up stage.

Aggregate(QualifiedName, NormalizedArgTypes)

A user-defined aggregate — disambiguated by argument types (aggregates are overloadable, like functions). The aggregate depends on its state function (SFUNC) and optional final function (FINALFUNC), both of which are managed NodeId::Function nodes.

Cast(QualifiedName, QualifiedName)

A CREATE CAST — identified by (source_type, target_type). Not schema-scoped; casts are database-global objects. Depends on the conversion function (when WITH FUNCTION) and on managed source/target types (when the types are user-defined and in the managed catalog).

TsDictionary(QualifiedName)

A CREATE TEXT SEARCH DICTIONARY — schema-scoped.

TsConfiguration(QualifiedName)

A CREATE TEXT SEARCH CONFIGURATION — schema-scoped. Depends on any managed NodeId::TsDictionary objects referenced in its token-type mappings.

Trait Implementations

impl Clone for NodeId

fn clone(&self) -> NodeId

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for NodeId

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for NodeId

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for NodeId

impl Hash for NodeId

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

Feeds this value into the given Hasher.

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

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for NodeId

fn cmp(&self, other: &NodeId) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for NodeId

fn eq(&self, other: &NodeId) -> 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 PartialOrd for NodeId

fn partial_cmp(&self, other: &NodeId) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl Serialize for NodeId

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
