Types

type Batch 

type Batch interface {
	KeyValueWriterDeleter

	// the keys, values, and deleted keys.
	Size() int

	// Write flushes any accumulated data to disk.

	// Replay replays the batch contents in the same order they were written
	// to the batch.

	// Inner returns a Batch writing to the inner database, if one exists. If
	// this batch is already writing to the base DB, then itself should be
	// returned.

}

Batch is a write-only database that commits changes to its host database when Write is called. A batch cannot be used concurrently.

	// NewBatch creates a write-only database that buffers changes to its host db
	// until a final write is called.
	NewBatch() Batch
}

Batcher wraps the NewBatch method of a backing data store.

type Compacter 

type Compacter interface {
	// Compact the underlying DB for the given key range.
	// Specifically, deleted and overwritten versions are discarded,
	// and the data is rearranged to reduce the cost of operations
	// needed to access the data. This operation should typically only
	// be invoked by users who understand the underlying implementation.
	//
	// A nil start is treated as a key before all keys in the DB.
	// And a nil limit is treated as a key after all keys in the DB.
	// Therefore if both are nil then it will compact entire DB.
	//
	// Note: [start] and [limit] are safe to modify and read after calling Compact.
	Compact(start []byte, limit []byte) error
}

Compacter wraps the Compact method of a backing data store.

type Database 

type Database interface {
	KeyValueReaderWriterDeleter
	Batcher
	Iteratee
	Compacter
	io.Closer
	health.Checker
}

Database contains all the methods required to allow handling different key-value data stores backing the database.

type Iteratee 

type Iteratee interface {
	// NewIterator creates an iterator over the entire keyspace contained within
	// the key-value database.
	NewIterator() Iterator

	// NewIteratorWithStart creates an iterator over a subset of database
	// content starting at a particular initial key.
	NewIteratorWithStart(start []byte) Iterator

	// NewIteratorWithPrefix creates an iterator over a subset of database
	// content with a particular key prefix.

	// NewIteratorWithStartAndPrefix creates an iterator over a subset of
	// database content with a particular key prefix starting at a specified
	// key.
	NewIteratorWithStartAndPrefix(start, prefix []byte) Iterator
}

Iteratee wraps the NewIterator methods of a backing data store.

type Iterator 

type Iterator interface {
	// Next moves the iterator to the next key/value pair. It returns whether
	// the iterator successfully moved to a new key/value pair.
	// The iterator may return false if the underlying database has been closed
	// before the iteration has completed, in which case future calls to Error()
	// must return [ErrClosed].
	Next() bool

	// Error returns any accumulated error. Exhausting all the key/value pairs
	// is not considered to be an error.
	// Error should be called after all key/value pairs have been exhausted ie.
	// after Next() has returned false.
	Error() error

	// Key returns the key of the current key/value pair, or nil if done.
	// If the database is closed, must still report the current contents.
	// Behavior is undefined after Release is called.
	Key() []byte

	// Value returns the value of the current key/value pair, or nil if done.
	// If the database is closed, must still report the current contents.
	// Behavior is undefined after Release is called.
	Value() []byte

	// Release releases associated resources. Release should always succeed and
	// can be called multiple times without causing error.
	Release()
}

Iterator iterates over a database's key/value pairs.

When it encounters an error any seek will return false and will yield no key/ value pairs. The error can be queried by calling the Error method. Calling Release is still necessary.

An iterator must be released after use, but it is not necessary to read an iterator until exhaustion. An iterator is not safe for concurrent use, but it is safe to use multiple iterators concurrently.

type IteratorError added in v1.9.9

type KeyValueDeleter interface {
	// Delete removes the key from the key-value data store.
	//
	// Note: [key] is safe to modify and read after calling Delete.
	Delete(key []byte) error
}

KeyValueDeleter wraps the Delete method of a backing data store.

type KeyValueReader 

type KeyValueReader interface {
	// Has retrieves if a key is present in the key-value data store.
	//
	// Note: [key] is safe to modify and read after calling Has.
	Has(key []byte) (bool, error)

	// Get retrieves the given key if it's present in the key-value data store.
	// Returns ErrNotFound if the key is not present in the key-value data store.
	//
	// Note: [key] is safe to modify and read after calling Get.
	// The returned byte slice is safe to read, but cannot be modified.
	Get(key []byte) ([]byte, error)
}

KeyValueReader wraps the Has and Get method of a backing data store.

type KeyValueReaderWriter 

type KeyValueReaderWriter interface {
	KeyValueReader
	KeyValueWriter
}

KeyValueReaderWriter allows read/write acccess to a backing data store.

type KeyValueReaderWriterDeleter 

type KeyValueReaderWriterDeleter interface {
	KeyValueReader
	KeyValueWriter
	KeyValueDeleter
}

KeyValueReaderWriterDeleter allows read/write/delete access to a backing data store.

type KeyValueWriter 

type KeyValueWriter interface {
	// Put inserts the given value into the key-value data store.
	//
	// Note: [key] and [value] are safe to modify and read after calling Put.
	//
	// If [value] is nil or an empty slice, then when it's retrieved
	// it may be nil or an empty slice.
	//
	// Similarly, a nil [key] is treated the same as an empty slice.
	Put(key []byte, value []byte) error
}

KeyValueWriter wraps the Put method of a backing data store.

type KeyValueWriterDeleter 

type KeyValueWriterDeleter interface {
	KeyValueWriter
