Types

type CanonicalKeyHandler 

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

CanonicalKeyHandler is a key handler which makes use of the canonical key for relations for dispatching.

type DirectKeyHandler 

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

DirectKeyHandler is a key handler that uses the relation name itself as the key.

func (DirectKeyHandler) ExpandDispatchKey 

func (b DirectKeyHandler) ExpandDispatchKey(_ context.Context, req *v1.DispatchExpandRequest) ([]byte, error)

func (DirectKeyHandler) LookupResources2CacheKey added in v0.0.3 

func (b DirectKeyHandler) LookupResources2CacheKey(_ context.Context, req *v1.DispatchLookupResources2Request) (DispatchCacheKey, error)

func (DirectKeyHandler) LookupResources2DispatchKey added in v0.0.3 

func (b DirectKeyHandler) LookupResources2DispatchKey(_ context.Context, req *v1.DispatchLookupResources2Request) ([]byte, error)

func (DirectKeyHandler) LookupResourcesCacheKey 

func (b DirectKeyHandler) LookupResourcesCacheKey(_ context.Context, req *v1.DispatchLookupResourcesRequest) (DispatchCacheKey, error)

func (DirectKeyHandler) LookupResourcesDispatchKey 

func (b DirectKeyHandler) LookupResourcesDispatchKey(_ context.Context, req *v1.DispatchLookupResourcesRequest) ([]byte, error)

func (DirectKeyHandler) LookupSubjectsCacheKey 

func (b DirectKeyHandler) LookupSubjectsCacheKey(_ context.Context, req *v1.DispatchLookupSubjectsRequest) (DispatchCacheKey, error)

func (DirectKeyHandler) LookupSubjectsDispatchKey 

func (b DirectKeyHandler) LookupSubjectsDispatchKey(_ context.Context, req *v1.DispatchLookupSubjectsRequest) ([]byte, error)

func (DirectKeyHandler) ReachableResourcesCacheKey 

func (b DirectKeyHandler) ReachableResourcesCacheKey(_ context.Context, req *v1.DispatchReachableResourcesRequest) (DispatchCacheKey, error)

func (DirectKeyHandler) ReachableResourcesDispatchKey 

func (b DirectKeyHandler) ReachableResourcesDispatchKey(_ context.Context, req *v1.DispatchReachableResourcesRequest) ([]byte, error)

type DispatchCacheKey 

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

DispatchCacheKey is a struct which holds the key representing a dispatch operation being dispatched or cached.

func (DispatchCacheKey) AsUInt64s 

func (dck DispatchCacheKey) AsUInt64s() (uint64, uint64)

AsUInt64s returns the cache key in the form of two uint64's. This method returns uint64s created from two distinct hashing algorithms, which should make the risk of key overlap incredibly unlikely.

func (DispatchCacheKey) KeyString added in v0.0.3 

func (dck DispatchCacheKey) KeyString() string

func (DispatchCacheKey) StableSumAsBytes 

func (dck DispatchCacheKey) StableSumAsBytes() []byte

StableSumAsBytes returns the stable portion of the dispatch cache key as bytes. Note that since this is only returning the result of one of the two sums, the returned bytes may not be fully unique for the input data.

type Handler 

type Handler interface {
	// CheckCacheKey computes the caching key for a Check operation.
	CheckCacheKey(ctx context.Context, req *v1.DispatchCheckRequest) (DispatchCacheKey, error)

	// LookupResourcesCacheKey computes the caching key for a LookupResources operation.
	LookupResourcesCacheKey(ctx context.Context, req *v1.DispatchLookupResourcesRequest) (DispatchCacheKey, error)

	// LookupResources2CacheKey computes the caching key for a LookupResources2 operation.
	LookupResources2CacheKey(ctx context.Context, req *v1.DispatchLookupResources2Request) (DispatchCacheKey, error)

	// LookupSubjectsCacheKey computes the caching key for a LookupSubjects operation.
	LookupSubjectsCacheKey(ctx context.Context, req *v1.DispatchLookupSubjectsRequest) (DispatchCacheKey, error)

	// ExpandCacheKey computes the caching key for an Expand operation.
	ExpandCacheKey(ctx context.Context, req *v1.DispatchExpandRequest) (DispatchCacheKey, error)

	// ReachableResourcesCacheKey computes the caching key for a ReachableResources operation.
	ReachableResourcesCacheKey(ctx context.Context, req *v1.DispatchReachableResourcesRequest) (DispatchCacheKey, error)

	// CheckDispatchKey computes the dispatch key for a Check operation.
	CheckDispatchKey(ctx context.Context, req *v1.DispatchCheckRequest) ([]byte, error)

	// LookupResourcesDispatchKey computes the dispatch key for a LookupResources operation.
	LookupResourcesDispatchKey(ctx context.Context, req *v1.DispatchLookupResourcesRequest) ([]byte, error)

	// LookupResources2DispatchKey computes the dispatch key for a LookupResources2 operation.
	LookupResources2DispatchKey(ctx context.Context, req *v1.DispatchLookupResources2Request) ([]byte, error)

	// LookupSubjectsDispatchKey computes the key for a LookupSubjects operation.
	LookupSubjectsDispatchKey(ctx context.Context, req *v1.DispatchLookupSubjectsRequest) ([]byte, error)

	// ExpandDispatchKey computes the dispatch key for an Expand operation.
	ExpandDispatchKey(ctx context.Context, req *v1.DispatchExpandRequest) ([]byte, error)

	// ReachableResourcesDispatchKey computes the key for a ReachableResources operation.
	ReachableResourcesDispatchKey(ctx context.Context, req *v1.DispatchReachableResourcesRequest) ([]byte, error)
}

Handler is an interface defining how keys are computed for dispatching and caching.
