Struct RelationRegistry 

pub struct RelationRegistry { /* private fields */ }

Relation lookup tables for one snapshot of the admin registration.

Implementations

impl RelationRegistry

pub fn empty() -> Self

Empty registry. Every lookup returns None.

pub fn from_admin_entries(entries: &[AdminEntry]) -> Self

Build the registry from the current admin entries. Silent on unknown targets / display fields — call validate after if you want those surfaced as errors.

pub fn belongs_to(&self, model: &str, field: &str) -> Option<&ResolvedRelation>

The ResolvedRelation for (model, field), if any.

pub fn belongs_to_of(&self, model: &str) -> &[ResolvedRelation]

Every forward relation owned by a source model.

pub fn has_many(&self, model: &str) -> &[InverseRelation]

Every incoming edge into model. Used by the inverse-panel renderer and the delete guard.

pub fn is_empty(&self) -> bool

true if the registry knows no relations at all.

pub fn validate(&self, entries: &[AdminEntry]) -> Vec<RegistryError>

Walk every stored relation and report declarations that reference models or columns not present in the current admin.

pub fn iter_belongs_to(&self) -> impl Iterator<Item = &ResolvedRelation>

A forward iterator over every ResolvedRelation in the registry, in deterministic order.
