Types

type Cache

type Cache struct {
	// contains filtered or unexported fields
}

func New

func New(m *model.Model) *Cache

New, create new model cache instance.

func (*Cache) AssignableRelations

func (c *Cache) AssignableRelations(on, sn ObjectName, sr ...RelationName) ([]RelationName, error)

AssignableRelations returns the set of relations that can occur between a given object type and a subject type, optionally with a subject relation.

If more than one subject relation is provided, AssignableRelations returns relations that match any of the given relations. For example, if the manifest has:

types:

tenant:
  relations:
    admin: group#member
    guest: group#guest

Then AssignableRelations("tenant", "group", "member", "guest") returns ["admin", "guest"].

func (*Cache) CanUpdate

func (c *Cache) CanUpdate(other *model.Model, stats *stts.Stats) error

func (*Cache) Check

func (c *Cache) Check(req *dsr.CheckRequest, relReader graph.RelationReader) (*dsr.CheckResponse, error)

func (*Cache) GetGraph

func (c *Cache) GetGraph(req *dsr.GetGraphRequest, relReader graph.RelationReader) (*dsr.GetGraphResponse, error)

func (*Cache) Metadata

func (c *Cache) Metadata() *model.Metadata

func (*Cache) ObjectExists

func (c *Cache) ObjectExists(on ObjectName) bool

ObjectExists, checks if given object type name exists in the model cache.

func (*Cache) PermissionExists

func (c *Cache) PermissionExists(on ObjectName, pn RelationName) bool

PermissionExists, checks if given permission, for the given object type, exists in the model cache.

func (*Cache) RelationExists

func (c *Cache) RelationExists(on ObjectName, rn RelationName) bool

RelationExists, checks if given relation type, for the given object type, exists in the model cache.

func (*Cache) UpdateModel

func (c *Cache) UpdateModel(m *model.Model) error

UpdateModel, swaps the cache model instance.

func (*Cache) ValidateRelation

func (c *Cache) ValidateRelation(relation *dsc.Relation) error

type ObjectName

type ObjectName = model.ObjectName

type RelationName

type RelationName = model.RelationName
