Types ¶
type CachedKeyValueStore ¶
type CachedKeyValueStore struct {
// contains filtered or unexported fields
}
CachedKeyValueStore is a key-value that all reads from the underlying store.
func NewCachedKeyValueStore ¶
func NewCachedKeyValueStore(kv lib.KeyValueStore) *CachedKeyValueStore
NewCachedKeyValueStore creates a new CachedKeyValueStore.
func (*CachedKeyValueStore) Get ¶
func (c *CachedKeyValueStore) Get(key common.Hash) common.Hash
Get gets the value for a key from either the cache or the underlying store. If the value is not in the cache, it is read from the underlying store and cached.
func (*CachedKeyValueStore) Set ¶
func (c *CachedKeyValueStore) Set(key, value common.Hash)
Set sets a key-value pair in the store. The write is NOT cached.
type HashedMemoryKeyValueStore ¶
type HashedMemoryKeyValueStore struct {
// contains filtered or unexported fields
}
HashedMemoryKeyValueStore is an in-memory key-value store that hashes keys before storing them.
func NewHashedMemoryKeyValueStore ¶
func NewHashedMemoryKeyValueStore() *HashedMemoryKeyValueStore
NewHashedMemoryKeyValueStore creates a new HashedMemoryKeyValueStore.
func (*HashedMemoryKeyValueStore) Delete ¶
func (kv *HashedMemoryKeyValueStore) Delete(key common.Hash)
Delete deletes a key from the store.
func (*HashedMemoryKeyValueStore) DeleteByKeyHash ¶
func (kv *HashedMemoryKeyValueStore) DeleteByKeyHash(keyHash common.Hash)
DeleteByKeyHash deletes a key from the store using the key hash.
func (*HashedMemoryKeyValueStore) ForEach ¶
func (kv *HashedMemoryKeyValueStore) ForEach(forEach func(keyHash, value common.Hash) bool)
ForEach calls a function for each key-value pair in the store.
func (*HashedMemoryKeyValueStore) Get ¶
func (kv *HashedMemoryKeyValueStore) Get(key common.Hash) common.Hash
Get gets the value for a key from the store.
func (*HashedMemoryKeyValueStore) GetByKeyHash ¶
func (kv *HashedMemoryKeyValueStore) GetByKeyHash(keyHash common.Hash) common.Hash
GetByKeyHash gets the value for a key from the store using the key hash.
func (*HashedMemoryKeyValueStore) Has ¶
func (kv *HashedMemoryKeyValueStore) Has(key common.Hash) bool
Has checks if a key exists in the store.
func (*HashedMemoryKeyValueStore) HasByKeyHash ¶
func (kv *HashedMemoryKeyValueStore) HasByKeyHash(keyHash common.Hash) bool
HasByKeyHash checks if a key exists in the store using the key hash.
func (*HashedMemoryKeyValueStore) Set ¶
func (kv *HashedMemoryKeyValueStore) Set(key common.Hash, value common.Hash)
Set sets a key-value pair in the store.
func (*HashedMemoryKeyValueStore) SetByKeyHash ¶
func (kv *HashedMemoryKeyValueStore) SetByKeyHash(keyHash, value common.Hash)
SetByKeyHash sets a key-value pair in the store using the key hash.
func (*HashedMemoryKeyValueStore) Size ¶
func (kv *HashedMemoryKeyValueStore) Size() int
Size returns the number of key-value pairs in the store.
type MemoryKeyValueStore ¶
type MemoryKeyValueStore struct {
// contains filtered or unexported fields
}
KeyValueStore is an in-memory key-value store.
func NewMemoryKeyValueStore ¶
func NewMemoryKeyValueStore() *MemoryKeyValueStore
NewMemoryKeyValueStore creates a new MemoryKeyValueStore.
func (*MemoryKeyValueStore) Delete ¶
func (kv *MemoryKeyValueStore) Delete(key common.Hash)
Delete deletes a key from the store.
func (*MemoryKeyValueStore) ForEach ¶
func (kv *MemoryKeyValueStore) ForEach(forEach func(key, value common.Hash) bool)
ForEach calls a function for each key-value pair in the store.
func (*MemoryKeyValueStore) Get ¶
func (kv *MemoryKeyValueStore) Get(key common.Hash) common.Hash
Get gets the value for a key from the store.
func (*MemoryKeyValueStore) Has ¶
func (kv *MemoryKeyValueStore) Has(key common.Hash) bool
Has checks if a key exists in the store.
func (*MemoryKeyValueStore) Set ¶
func (kv *MemoryKeyValueStore) Set(key common.Hash, value common.Hash)
Set sets a key-value pair in the store.
func (*MemoryKeyValueStore) Size ¶
func (kv *MemoryKeyValueStore) Size() int
Size returns the number of key-value pairs in the store.
type StagedKeyValueStore ¶
type StagedKeyValueStore struct {
// contains filtered or unexported fields
}
StagedKeyValueStore is a key-value store that stages writes to the underlying store until commit is called.
func NewStagedKeyValueStore ¶
func NewStagedKeyValueStore(kv lib.KeyValueStore) *StagedKeyValueStore
NewStagedKeyValueStore creates a new StagedKeyValueStore.
func (*StagedKeyValueStore) Commit ¶
func (s *StagedKeyValueStore) Commit()
Commit writes the staged key-value pairs to the underlying store.
func (*StagedKeyValueStore) Get ¶
func (s *StagedKeyValueStore) Get(key common.Hash) common.Hash
Get gets the value for a key from the store. If the key is staged, the staged value is returned.
func (*StagedKeyValueStore) Revert ¶
func (s *StagedKeyValueStore) Revert()
Revert discards the staged key-value pairs.
func (*StagedKeyValueStore) Set ¶
func (s *StagedKeyValueStore) Set(key, value common.Hash)
