Functions ¶
func Exclusion ¶
func Exclusion(start *core.ObjectAndRelation, children ...*core.RelationTupleTreeNode) *core.RelationTupleTreeNode
Exclusion constructs a RelationTupleTreeNode exclusion operation.
func HasThis ¶
func HasThis(rewrite *core.UsersetRewrite) (bool, error)
HasThis returns true if there exists a `_this` node anywhere within the given rewrite. If the rewrite is nil, returns false.
func Intersection ¶
func Intersection(start *core.ObjectAndRelation, children ...*core.RelationTupleTreeNode) *core.RelationTupleTreeNode
Intersection constructs a RelationTupleTreeNode intersection operation.
func Leaf ¶
func Leaf(start *core.ObjectAndRelation, subjects ...*core.DirectSubject) *core.RelationTupleTreeNode
Leaf constructs a RelationTupleTreeNode leaf.
func Union ¶
func Union(start *core.ObjectAndRelation, children ...*core.RelationTupleTreeNode) *core.RelationTupleTreeNode
Union constructs a RelationTupleTreeNode union operation.
func WalkRewrite ¶
func WalkRewrite(rewrite *core.UsersetRewrite, handler WalkHandler) (interface{}, error)
WalkRewrite walks a userset rewrite tree, invoking the handler found on each node of the tree until the handler returns a non-nil value, which is in turn returned from this function. Returns nil if no valid value was found. If the rewrite is nil, returns nil.
Types ¶
type WalkHandler ¶
type WalkHandler func(childOneof *core.SetOperation_Child) (interface{}, error)
WalkHandler is a function invoked for each node in the rewrite tree. If it returns non-nil, that value is returned from the walk. Otherwise, the walk continues.
