Types

type BaseSubjectSet 

type BaseSubjectSet[T Subject[T]] struct {
	// contains filtered or unexported fields
}

BaseSubjectSet defines a set that tracks accessible subjects, their exclusions (if wildcards), and all conditional expressions applied due to caveats.

It is generic to allow other implementations to define the kind of tracking information associated with each subject.

NOTE: Unlike a traditional set, unions between wildcards and a concrete subject will result in *both* being present in the set, to maintain the proper set semantics around wildcards.

func NewBaseSubjectSet 

func NewBaseSubjectSet[T Subject[T]](constructor constructor[T]) BaseSubjectSet[T]

NewBaseSubjectSet creates a new base subject set for use underneath well-typed implementation.

The constructor function returns a new instance of type T for a particular subject ID.

func (BaseSubjectSet[T]) Add 

func (bss BaseSubjectSet[T]) Add(foundSubject T) error

Add adds the found subject to the set. This is equivalent to a Union operation between the existing set of subjects and a set containing the single subject, but modifies the set *in place*.

func (BaseSubjectSet[T]) AsSlice 

func (bss BaseSubjectSet[T]) AsSlice() []T

AsSlice returns the contents of the subject set as a slice of found subjects.

func (BaseSubjectSet[T]) Clone 

func (bss BaseSubjectSet[T]) Clone() BaseSubjectSet[T]

Clone returns a clone of this subject set. Note that this is a shallow clone. NOTE: Should only be used when performance is not a concern.

func (BaseSubjectSet[T]) Get 

func (bss BaseSubjectSet[T]) Get(id string) (T, bool)

Get returns the found subject with the given ID in the set, if any.

func (BaseSubjectSet[T]) IntersectionDifference 

func (bss BaseSubjectSet[T]) IntersectionDifference(other BaseSubjectSet[T]) error

IntersectionDifference performs an intersection between this set and the other set, modifying this set *in place*.

func (BaseSubjectSet[T]) IsEmpty 

func (bss BaseSubjectSet[T]) IsEmpty() bool

IsEmpty returns whether the subject set is empty.

func (BaseSubjectSet[T]) MustAdd added in v1.16.0 

func (bss BaseSubjectSet[T]) MustAdd(foundSubject T)

MustAdd adds the found subject to the set. This is equivalent to a Union operation between the existing set of subjects and a set containing the single subject, but modifies the set *in place*.

func (BaseSubjectSet[T]) MustIntersectionDifference added in v1.16.0 

func (bss BaseSubjectSet[T]) MustIntersectionDifference(other BaseSubjectSet[T])

MustIntersectionDifference performs an intersection between this set and the other set, modifying this set *in place*.

func (BaseSubjectSet[T]) MustUnionWithSet added in v1.16.0 

func (bss BaseSubjectSet[T]) MustUnionWithSet(other BaseSubjectSet[T])

MustUnionWithSet performs a union operation between this set and the other set, modifying this set *in place*.

func (BaseSubjectSet[T]) Subtract 

func (bss BaseSubjectSet[T]) Subtract(toRemove T)

Subtract subtracts the given subject found the set.

func (BaseSubjectSet[T]) SubtractAll 

func (bss BaseSubjectSet[T]) SubtractAll(other BaseSubjectSet[T])

SubtractAll subtracts the other set of subjects from this set of subtracts, modifying this set *in place*.

func (BaseSubjectSet[T]) UnionWith 

func (bss BaseSubjectSet[T]) UnionWith(foundSubjects []T) error

UnionWith adds the given subjects to this set, via a union call.

func (BaseSubjectSet[T]) UnionWithSet 

func (bss BaseSubjectSet[T]) UnionWithSet(other BaseSubjectSet[T]) error

UnionWithSet performs a union operation between this set and the other set, modifying this set *in place*.

func (BaseSubjectSet[T]) UnsafeRemoveExact 

func (bss BaseSubjectSet[T]) UnsafeRemoveExact(foundSubject T)

UnsafeRemoveExact removes the *exact* matching subject, with no wildcard handling. This should ONLY be used for testing.

func (BaseSubjectSet[T]) WithParentCaveatExpression 

func (bss BaseSubjectSet[T]) WithParentCaveatExpression(parentCaveatExpr *core.CaveatExpression) BaseSubjectSet[T]

WithParentCaveatExpression returns a copy of the subject set with the parent caveat expression applied to all members of this set.

type Subject 

type Subject[T any] interface {
	// GetSubjectId returns the ID of the subject. For wildcards, this should be `*`.
	GetSubjectId() string

	// GetCaveatExpression returns the caveat expression for this subject, if it is conditional.
	GetCaveatExpression() *core.CaveatExpression

	// GetExcludedSubjects returns the list of subjects excluded. Must only have values
	// for wildcards and must never be nested.
	GetExcludedSubjects() []T
}

Subject is a subject that can be placed into a BaseSubjectSet. It is defined in a generic manner to allow implementations that wrap BaseSubjectSet to add their own additional bookkeeping to the base implementation.

type SubjectByTypeSet 

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

SubjectByTypeSet is a set of SubjectSet's, grouped by their subject types.

func NewSubjectByTypeSet 

func NewSubjectByTypeSet() *SubjectByTypeSet

NewSubjectByTypeSet creates and returns a new SubjectByTypeSet.

func (*SubjectByTypeSet) AddConcreteSubject 

func (s *SubjectByTypeSet) AddConcreteSubject(subject *core.ObjectAndRelation) error

AddConcreteSubject adds a non-caveated subject to the set.

func (*SubjectByTypeSet) AddSubject 

func (s *SubjectByTypeSet) AddSubject(subject *core.ObjectAndRelation, caveat *core.ContextualizedCaveat) error

AddSubject adds the specified subject to the set.

func (*SubjectByTypeSet) AddSubjectOf 

func (s *SubjectByTypeSet) AddSubjectOf(relationship *core.RelationTuple) error

AddSubjectOf adds the subject found in the given relationship, along with its caveat.

func (*SubjectByTypeSet) ForEachType 

func (s *SubjectByTypeSet) ForEachType(handler func(rr *core.RelationReference, subjects SubjectSet))

ForEachType invokes the handler for each type of ObjectAndRelation found in the set, along with all IDs of objects of that type.

func (*SubjectByTypeSet) IsEmpty 

func (s *SubjectByTypeSet) IsEmpty() bool

IsEmpty returns true if the set is empty.

func (*SubjectByTypeSet) Len

type SubjectSet 

type SubjectSet struct {
	BaseSubjectSet[*v1.FoundSubject]
}

SubjectSet defines a set that tracks accessible subjects.

NOTE: Unlike a traditional set, unions between wildcards and a concrete subject will result in *both* being present in the set, to maintain the proper set semantics around wildcards.
