Struct DependencyGraph 

pub struct DependencyGraph { /* private fields */ }

Implementations

impl DependencyGraph

pub fn new(edges: impl IntoIterator<Item = Dependency>) -> Self

Index the dependencies in the order they were recorded. pg_depend keeps a dependency that two recordings of one object share, such as a routine’s argument type that its body names again, and the deletion search visits the object once either way.

pub fn edges(&self) -> &[Dependency]

pub fn references_of( &self, object: ObjectAddress, ) -> impl Iterator<Item = &Dependency>

What object depends on; for a whole object, what any of its columns depends on too.

pub fn dependents_of( &self, object: ObjectAddress, ) -> impl Iterator<Item = &Dependency>

What depends on object; for a whole object, what depends on any of its columns too.
