Module relations 

Relationship types (BelongsTo<T>, HasMany<T>, HasOne<T>).

These types serve as container wrappers for navigation properties, analogous to how EFCore represents navigation properties in the model.

They are pure marker/container types and do NOT impose entity trait bounds — the constraint belongs at the usage site (DbContext, builders), not on the container itself.

Structs

BelongsTo

Represents a “belongs-to” navigation — the dependent side of a one-to-many or one-to-one relationship where the foreign key lives on this entity.

HasMany

Represents a “has-many” navigation — a collection of related entities.

HasOne

Represents a “has-one” navigation — a single related entity where the foreign key lives on the other side.

Enums

DeleteBehavior

Specifies the delete behavior for a relationship. Corresponds to EFCore’s DeleteBehavior.
