示例#1

文件： db.go 项目： olehz/hyperleveldb-go

// CompactRange runs a manual compaction on the Range of keys given. This is
// not likely to be needed for typical usage.
func (db *DB) CompactRange(r Range) {
	var start, limit *C.char
	if len(r.Start) != 0 {
		start = (*C.char)(unsafe.Pointer(&r.Start[0]))
	}
	if len(r.Limit) != 0 {
		limit = (*C.char)(unsafe.Pointer(&r.Limit[0]))
	}
	C.leveldb_compact_range(
		db.Ldb, start, C.size_t(len(r.Start)), limit, C.size_t(len(r.Limit)))
}
