Types ¶
type Batch ¶
type Batch struct {
// contains filtered or unexported fields
}
Batch is some kind of temporary storage in RAM. Once you perform a series of operations, call the Write() method to unload information from the batch into the database.
func (*Batch) CreateTableBatch ¶
CreateTableBatch creates new tablebatch instance.
type Batcher ¶
type Batcher interface {
// Put puts bytes to the batch.
Put(key, value []byte) error
// PutObject puts object to the batch.
PutObject(key []byte, obj interface{}) error
// Delete deletes value by key from the batch.
Delete(key []byte) error
// Write writes data from batch to the database
Write() error
// Reset resets batch.
Reset()
// CreateTableBatch creates new tablebatch instance.
CreateTableBatch(prefix []byte) Batcher
}
Batcher is a general representation of the batch, which can both tablebatch and batch.
type Corrector ¶
type Corrector interface {
// Put puts bytes to the database.
Put(key, value []byte) error
// PutObject puts object to the database.
PutObject(key []byte, obj interface{}) error
// Delete deletes value by key from the database.
Delete(key []byte) error
// Get gets bytes from the database.
Get(key []byte) ([]byte, error)
// GetObject gets object from the database.
GetObject(key []byte, obj interface{}) error
// Has checks the presence of an element in the database.
Has(key []byte) (bool, error)
}
Corrector is a combination of Reader and Writer.
type Db ¶
type Db struct {
// contains filtered or unexported fields
}
Db is wrapper over the standard leveldb.DB.
func (*Db) CreateTable ¶
CreateTable creates new table instance.
func (*Db) NewIterator ¶
NewIterator creates new iterator instance.
func (*Db) NewIteratorPrefix ¶
NewIteratorPrefix creates new iterator instance with prefix.
type Reader ¶
type Reader interface {
// Get gets bytes from the database.
Get(key []byte) ([]byte, error)
// GetObject gets object from the database.
GetObject(key []byte, obj interface{}) error
// Has checks the presence of an element in the database.
Has(key []byte) (bool, error)
}
Reader is a database object with read access.
type Tbl ¶
type Tbl struct {
// contains filtered or unexported fields
}
Tbl will in fact add a prefix to any records.
type TblBatch ¶
type TblBatch struct {
// contains filtered or unexported fields
}
TblBatch it's the same as batch, but with a prefix.
func (*TblBatch) CreateTableBatch ¶
CreateTableBatch creates new tablebatch instance.
type Writer ¶
type Writer interface {
// Put puts bytes to the database.
Put(key, value []byte) error
// PutObject puts object to the database.
PutObject(key []byte, obj interface{}) error
// Delete deletes value by key from the database.
Delete(key []byte) error
}
Writer is a database object with write access.
