Types

type BufferedKVStore

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

BufferedKVStore is a KVStore backed by a given KVStoreReader. Writes are cached in-memory; reads are delegated to the backing store for unmodified keys.

func NewBufferedKVStore

func NewBufferedKVStore(r kv.KVStoreReader) *BufferedKVStore

func NewBufferedKVStoreForMutations

func NewBufferedKVStoreForMutations(r kv.KVStoreReader, m *Mutations) *BufferedKVStore

func (*BufferedKVStore) Clone

func (b *BufferedKVStore) Clone() *BufferedKVStore

func (*BufferedKVStore) DangerouslyDumpToDict

func (b *BufferedKVStore) DangerouslyDumpToDict() dict.Dict

DangerouslyDumpToDict returns a Dict with the whole contents of the backing store + applied mutations.

func (*BufferedKVStore) DangerouslyDumpToString

func (b *BufferedKVStore) DangerouslyDumpToString() string

iterates over all key-value pairs in KVStore

func (*BufferedKVStore) Del

func (b *BufferedKVStore) Del(key kv.Key)

func (*BufferedKVStore) Get

func (b *BufferedKVStore) Get(key kv.Key) []byte

func (*BufferedKVStore) Has

func (b *BufferedKVStore) Has(key kv.Key) bool

func (*BufferedKVStore) Iterate

func (b *BufferedKVStore) Iterate(prefix kv.Key, f func(key kv.Key, value []byte) bool)

func (*BufferedKVStore) IterateKeys

func (b *BufferedKVStore) IterateKeys(prefix kv.Key, f func(key kv.Key) bool)

func (*BufferedKVStore) IterateKeysSorted

func (b *BufferedKVStore) IterateKeysSorted(prefix kv.Key, f func(key kv.Key) bool)

func (*BufferedKVStore) IterateSorted

func (b *BufferedKVStore) IterateSorted(prefix kv.Key, f func(key kv.Key, value []byte) bool)

func (*BufferedKVStore) Mutations

func (b *BufferedKVStore) Mutations() *Mutations

func (*BufferedKVStore) Set

func (b *BufferedKVStore) Set(key kv.Key, value []byte)

type Mutations

type Mutations struct {
	Sets map[kv.Key][]byte
	Dels map[kv.Key]struct{}
}

Mutations is a set of mutations: one for each key It provides a deterministic serialization
