Struct DeletionTargets 

pub struct DeletionTargets { /* private fields */ }

The objects to delete in deletion order: every dependent before the object it depends on.

Implementations

impl DeletionTargets

pub fn collect( graph: &DependencyGraph, originals: &[ObjectAddress], describe: Describe<'_>, ) -> Result<Self, SQLError>

performMultipleDeletions’ search: the named objects and everything that depends on them. An object that is internal to another named object is deleted with its owner; one that is internal to an unnamed object reports 2BP01 as findDependentObjects does.

pub fn targets(&self) -> &[DeletionTarget]

pub fn report( &self, cascade: bool, original: Option<ObjectAddress>, describe: Describe<'_>, ) -> Result<Option<CascadeNotice>, SQLError>

reportDependentObjects: reject a RESTRICT drop that would delete an object reached through a normal dependency, or describe what a cascading drop deletes. original names the single object the command drops.
