impl DependencyGraph
pub fn new() -> Self
pub fn edges(&self) -> &[DependencyEdge]
pub fn add_edge(&mut self, edge: DependencyEdge)
Sourcepub fn indexes_are_valid(&self) -> bool
pub fn indexes_are_valid(&self) -> bool
Confirms that every derived lookup points at the canonical edge list. This is intentionally cheap to call from invariant tests, not hot paths.
pub fn cascade_edges(&self, id: &ObjectId) -> Vec<&DependencyEdge>
pub fn is_referenced_by_view(&self, id: &ObjectId) -> Vec<&ObjectId>
pub fn is_referenced_by_fk(&self, id: &ObjectId) -> Vec<(&ObjectId, u64)>
pub fn is_referenced_by_index(&self, id: &ObjectId) -> Vec<&ObjectId>
pub fn partitions_of(&self, id: &ObjectId) -> Vec<&ObjectId>
pub fn resolve_rename<'a>(&'a self, id: &'a ObjectId) -> &'a ObjectId
pub fn check_partition_cycle(&self, parent: &ObjectId, child: &ObjectId) -> bool
Sourcepub fn propagate_relation_rename(
&mut self,
old_id: &ObjectId,
new_id: &ObjectId,
)
pub fn propagate_relation_rename( &mut self, old_id: &ObjectId, new_id: &ObjectId, )
Propagate a relation rename through relation-to-relation edges.
Dependency endpoints are intentionally updated by edge kind rather than
by blindly comparing ObjectIds. ObjectId carries no catalog kind,
and publications are represented by a synthetic public/<name> ID, so
a generic endpoint rewrite can otherwise corrupt an unrelated edge when
two namespaces happen to share a name.
Sourcepub fn propagate_index_rename(&mut self, old_id: &ObjectId, new_id: &ObjectId)
pub fn propagate_index_rename(&mut self, old_id: &ObjectId, new_id: &ObjectId)
Propagate an index rename. Indexes are dependent endpoints of their
IndexOnRelation edges; they are not relation references.
Sourcepub fn propagate_sequence_rename(
&mut self,
old_id: &ObjectId,
new_id: &ObjectId,
)
pub fn propagate_sequence_rename( &mut self, old_id: &ObjectId, new_id: &ObjectId, )
Propagate a sequence rename only through sequence ownership edges.
Sourcepub fn propagate_trigger_rename(&mut self, old_id: &ObjectId, new_id: &ObjectId)
pub fn propagate_trigger_rename(&mut self, old_id: &ObjectId, new_id: &ObjectId)
Propagate a trigger rename through its trigger edge and payload.
Sourcepub fn propagate_function_rename(
&mut self,
old_id: &ObjectId,
new_id: &ObjectId,
)
pub fn propagate_function_rename( &mut self, old_id: &ObjectId, new_id: &ObjectId, )
Propagate a function rename through trigger dependency payloads.
Sourcepub fn propagate_rename(&mut self, old_id: &ObjectId, new_id: &ObjectId)
pub fn propagate_rename(&mut self, old_id: &ObjectId, new_id: &ObjectId)
Backwards-compatible relation rename entry point.
New callers should use the typed helpers above. Keeping this method relation-scoped prevents the old all-endpoints behavior from silently rewriting sequence, trigger, function, or publication identity data.
pub fn triggers_on(&self, table_id: &ObjectId) -> Vec<&DependencyEdge>
pub fn triggers_for_function( &self, function_id: &ObjectId, ) -> Vec<&DependencyEdge>
