示例#1

文件： options.go 项目： C0rWin/fabric

// SetComparator sets the comparator which define the order of keys in the table.
// Default: a comparator that uses lexicographic byte-wise ordering
func (opts *Options) SetComparator(value Comparator) {
	if nc, ok := value.(nativeComparator); ok {
		opts.ccmp = nc.c
	} else {
		idx := registerComperator(value)
		opts.ccmp = C.gorocksdb_comparator_create(C.uintptr_t(idx))
	}
	C.rocksdb_options_set_comparator(opts.c, opts.ccmp)
