Variables

var Decorator = &decorator{}

Decorator is an off-ledger decorator that ensures the key is the hash of the value.

Functions

func GetCASKey

func GetCASKey(content []byte, version CIDVersion, codec, mhType uint64) (string, error)

GetCASKey returns the key which will be used in the data store to store the value.

func GetCID

func GetCID(content []byte, version CIDVersion, codec, mhType uint64) (string, error)

GetCID returns the content ID (CID) of the value using the given CID version, codec, and multi-hash type.

func ValidateCID

func ValidateCID(id string) error

ValidateCID validates the given content ID

func ValidateDatastoreKey

func ValidateDatastoreKey(key string, value []byte) error

ValidateDatastoreKey validates the given data store key, ensuring that it conforms to the encoding used by the DCAS store store

func Validator

func Validator(_, _, _, key string, value []byte) error

Validator is an off-ledger validator that validates the CAS key against the value

Types

type CIDVersion

type CIDVersion = uint64

CIDVersion specifies the version of the content ID (CID)

const (
	// CIDV0 content ID (CID) version 0
	CIDV0 CIDVersion = 0
	// CIDV1 content ID (CID) version 1
	CIDV1 CIDVersion = 1
)
