Types

type Analyser 

type Analyser interface {
	GetDBReadTime() int
	GetDBWriteCount() int
	GetDBReadCount() int
	GetNodeReadCount() int
	GetFlatKVReadTime() int
	GetFlatKVWriteTime() int
	GetFlatKVReadCount() int
	GetFlatKVWriteCount() int
	ResetCount()
}

type CacheKVStore 

type CacheKVStore interface {
	KVStore
	CacheManager
	// Writes operations to underlying KVStore
	Write()
}

CacheKVStore cache-wraps a KVStore. After calling .Write() on the CacheKVStore, all previously created CacheKVStores on the object expire.

type CacheManager 

type CacheManager interface {
	IteratorCache(isdirty bool, cb func(key string, value []byte, isDirty bool, isDelete bool, storeKey StoreKey) bool, sKey StoreKey) bool
}

type CacheMultiStore 

type CacheMultiStore interface {
	MultiStore
	CacheManager
	Write() // Writes operations to underlying KVStore
}

type CacheWrap 

type CacheWrap interface {
	CacheManager

type StoreKey 

type StoreKey interface {
	Name() string
	String() string
}

StoreKey is a key used to index stores in a MultiStore.

type StoreRename 

type StoreRename struct {
	OldKey string `json:"old_key"`
	NewKey string `json:"new_key"`
}

StoreRename defines a name change of a sub-store. All data previously under a PrefixStore with OldKey will be copied to a PrefixStore with NewKey, then deleted from OldKey store.

type StoreType 

type StoreType int

kind of store 

const (
	//nolint
	StoreTypeMulti StoreType = iota
	StoreTypeDB
	StoreTypeIAVL
	StoreTypeTransient
	StoreTypeMPT
	StoreTypeMemory
)

type StoreUpgrades 

type StoreUpgrades struct {
	Added   []string      `json:"added"`
	Renamed []StoreRename `json:"renamed"`
	Deleted []string      `json:"deleted"`
}

StoreUpgrades defines a series of transformations to apply the multistore db upon load

func (*StoreUpgrades) IsAdded 

func (s *StoreUpgrades) IsAdded(key string) bool

IsAdded returns true if the given key should be added

func (*StoreUpgrades) IsDeleted 

func (s *StoreUpgrades) IsDeleted(key string) bool

IsDeleted returns true if the given key should be deleted

func (*StoreUpgrades) RenamedFrom 

func (s *StoreUpgrades) RenamedFrom(key string) string

RenamedFrom returns the oldKey if it was renamed Returns "" if it was not renamed

type TraceContext 

type TraceContext map[string]interface{}

TraceContext contains TraceKVStore context data. It will be written with every trace operation.

type TransientStoreKey 

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

TransientStoreKey is used for indexing transient stores in a MultiStore

func NewTransientStoreKey 

func NewTransientStoreKey(name string) *TransientStoreKey

Constructs new TransientStoreKey Must return a pointer according to the ocap principle

func (*TransientStoreKey) Name 

func (key *TransientStoreKey) Name() string

Implements StoreKey

func (*TransientStoreKey) String 

func (key *TransientStoreKey) String() string

Implements StoreKey

type VersionCallback added in v1.5.0 

type VersionCallback = func(name string, version int64)

type VersionFilter added in v1.3.0 

type VersionFilter func(h int64) func(callback VersionCallback)

type WriteListener added in v1.3.0 

type WriteListener interface {
	// if value is nil then it was deleted
	// storeKey indicates the source KVStore, to facilitate using the the same WriteListener across separate KVStores
	// delete bool indicates if it was a delete; true: delete, false: set
	OnWrite(storeKey StoreKey, key []byte, value []byte, delete bool) error
}

WriteListener interface for streaming data out from a listenkv.Store
