Types

type IDGenerator

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

func NewIDGenerator

func NewIDGenerator(sg StoreGetter, idkey []byte) IDGenerator

NewIDGenerator creates a new ID generator. IT uses idKey as a main

func (IDGenerator) GetLastID

func (i IDGenerator) GetLastID(ctx sdk.Context, name string) uint64

getLastID returns the last id that was inserted for the given name. If one does not exist, then it returns 0,

func (IDGenerator) IncrementNextID

func (i IDGenerator) IncrementNextID(ctx sdk.Context, name string) uint64

incrementNextID returns new ID which can now be used for referencing data and increments the counter internally. It returns the newly inserted ID.

func (IDGenerator) Zero

func (i IDGenerator) Zero() bool

type StoreGetter

type StoreGetter interface {
	Store(ctx sdk.Context) sdk.KVStore
}

func SimpleStoreGetter

func SimpleStoreGetter(s sdk.KVStore) StoreGetter

type StoreGetterFn

type StoreGetterFn func(ctx sdk.Context) sdk.KVStore

func (StoreGetterFn) Store

func (s StoreGetterFn) Store(ctx sdk.Context) sdk.KVStore
