Functions

func AnnotateNamespace added in v1.7.0 

func AnnotateNamespace(ts *typesystem.ValidatedNamespaceTypeSystem) error

AnnotateNamespace annotates the namespace in the type system with computed aliasing and cache key metadata for more efficient dispatching.

func CheckNamespaceAndRelation added in v1.8.0 

func CheckNamespaceAndRelation(
	ctx context.Context,
	namespace string,
	relation string,
	allowEllipsis bool,
	ds datastore.Reader,
) error

CheckNamespaceAndRelation checks that the specified namespace and relation exist in the datastore.

Returns datastore.ErrNamespaceNotFound if the namespace cannot be found. Returns ErrRelationNotFound if the relation was not found in the namespace. Returns the direct downstream error for all other unknown error.

func CheckNamespaceAndRelations added in v1.22.0 

func CheckNamespaceAndRelations(ctx context.Context, checks []TypeAndRelationToCheck, ds datastore.Reader) error

CheckNamespaceAndRelations ensures that the given namespace+relation checks all succeed. If any fail, returns an error.

Returns ErrNamespaceNotFound if the namespace cannot be found. Returns ErrRelationNotFound if the relation was not found in the namespace. Returns the direct downstream error for all other unknown error.

func ListReferencedNamespaces added in v1.12.0 

func ListReferencedNamespaces(nsdefs []*core.NamespaceDefinition) []string

ListReferencedNamespaces returns the names of all namespaces referenced in the given namespace definitions. This includes the namespaces themselves, as well as any found in type information on relations.

	ctx context.Context,
	namespace string,
	relation string,
	ds datastore.Reader,
) (*core.NamespaceDefinition, *core.Relation, error)

ReadNamespaceAndRelation checks that the specified namespace and relation exist in the datastore.

Returns ErrNamespaceNotFound if the namespace cannot be found. Returns ErrRelationNotFound if the relation was not found in the namespace. Returns the direct downstream error for all other unknown error.

func ReadNamespaceAndTypes added in v1.8.0 

func ReadNamespaceAndTypes(
	ctx context.Context,
	nsName string,
	ds datastore.Reader,
) (*core.NamespaceDefinition, *typesystem.TypeSystem, error)

ReadNamespaceAndTypes reads a namespace definition, version, and type system and returns it if found.

func ValidateCaveatDefinition added in v1.14.0 

func ValidateCaveatDefinition(caveat *core.CaveatDefinition) error
