type Batch ¶

type Batch interface {
	Writer
	Delete(key []byte) error
	Commit() error
	Close() error
}

Batch represents an atomic batch of operations. All operations in a batch are performed atomically.

type Iterator ¶

type Iterator interface {
	Next() bool
	Key() []byte
	Value() ([]byte, error)
	Valid() bool
	Close() error
}

Iterator provides sequential access over a range of key-value pairs. Iterators must be closed after use.

type KVStore ¶

type KVStore interface {
	Writer
	Get(key []byte) ([]byte, error)
	Delete(key []byte) error
	NewBatch() Batch
	NewIterator(start, end []byte) (Iterator, error)
	Close() error
}

KVStore represents a key-value storage interface providing basic operations for data manipulation and iteration.

type Writer ¶

type Writer interface {
	Put(key []byte, value []byte) error
}
