Types

type Store

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

Store Implements types.KVStore and CommitStore.

func UnsafeNewStore

func UnsafeNewStore(tree *iavl.MutableTree, numRecent int64, storeEvery int64) *Store

CONTRACT: tree should be fully loaded. nolint: unparam

func (*Store) CacheWrap

func (st *Store) CacheWrap() types.CacheWrap

Implements Store.

func (*Store) CacheWrapWithTrace

func (st *Store) CacheWrapWithTrace(w io.Writer, tc types.TraceContext) types.CacheWrap

CacheWrapWithTrace implements the Store interface.

func (*Store) Commit

func (st *Store) Commit() types.CommitID

Implements Committer.

func (*Store) Delete

func (st *Store) Delete(key []byte)

Implements types.KVStore.

func (*Store) Get

func (st *Store) Get(key []byte) (value []byte)

Implements types.KVStore.

func (*Store) GetStoreType

func (st *Store) GetStoreType() types.StoreType

Implements Store.

func (*Store) Has

func (st *Store) Has(key []byte) (exists bool)

Implements types.KVStore.

func (*Store) Iterator

func (st *Store) Iterator(start, end []byte) types.Iterator

Implements types.KVStore.

func (*Store) LastCommitID

func (st *Store) LastCommitID() types.CommitID

Implements Committer.

func (*Store) Query

func (st *Store) Query(req abci.RequestQuery) (res abci.ResponseQuery)

Query implements ABCI interface, allows queries

by default we will return from (latest height -1), as we will have merkle proofs immediately (header height = data height + 1) If latest-1 is not present, use latest (which must be present) if you care to have the latest data to see a tx results, you must explicitly set the height you want to see

func (*Store) ReverseIterator

func (st *Store) ReverseIterator(start, end []byte) types.Iterator

Implements types.KVStore.

func (*Store) Set

func (st *Store) Set(key, value []byte)

Implements types.KVStore.

func (*Store) SetPruning

func (st *Store) SetPruning(opt types.PruningOptions)

Implements Committer.

func (*Store) VersionExists

func (st *Store) VersionExists(version int64) bool

VersionExists returns whether or not a given version is stored.
