Functions

func IsECContainer

func IsECContainer(cnr containerSDK.Container) bool

IsECContainer returns True if container has erasure coding policy.

func IsIndexedContainer

func IsIndexedContainer(cnr containerSDK.Container) bool

IsIndexedContainer returns True if container attributes should be indexed.

func WasRemoved

func WasRemoved(s Source, cid cid.ID) (bool, error)

WasRemoved checks whether the container ever existed or it just has not been created yet at the current epoch.

Types

type Container

type Container struct {
	// Container structure.
	Value container.Container

	// Signature of the Value.
	Signature frostfscrypto.Signature

	// Session within which Value was created. Nil means session absence.
	Session *session.Container
}

Container groups information about the FrostFS container stored in the FrostFS network.

type DelInfo

type DelInfo struct {
	// Container owner.
	Owner user.ID

	// Epoch indicates when the container was removed.
	Epoch uint64
}

DelInfo contains info about removed container.

type EACL

type EACL struct {
	// Extended ACL structure.
	Value *eacl.Table

	// Signature of the Value.
	Signature frostfscrypto.Signature

	// Session within which Value was set. Nil means session absence.
	Session *session.Container
}

EACL groups information about the FrostFS container's extended ACL stored in the FrostFS network.

type Info

type Info struct {
	Indexed bool
	Removed bool
}

type InfoProvider

type InfoProvider interface {
	Info(id cid.ID) (Info, error)
}

func NewInfoProvider

func NewInfoProvider(sourceFactory func() (Source, error)) InfoProvider

type RemovalWitness

type RemovalWitness struct {
	// ContainerID returns the identifier of the container
	// to be removed.
	ContainerID cid.ID

	// Signature the signature of the container identifier.
	Signature *refs.Signature

	// SessionToken the token of the session within
	// which the container was removed.
	SessionToken *session.Container
}

RemovalWitness groups the information required to prove and verify the removal of a container.

type Source

type Source interface {
	// Get reads the container from the storage by its identifier.
	// It returns the pointer to the requested container and any error encountered.
	//
	// Get must return exactly one non-nil value.
	// Get must return an error of type apistatus.ContainerNotFound if the container is not in the storage.
	//
	// Implementations must not retain the container pointer and modify
	// the container through it.
	Get(cid.ID) (*Container, error)

	DeletionInfo(cid.ID) (*DelInfo, error)
}

Source is an interface that wraps basic container receiving method.
