Types ¶
type Etcd ¶
type Etcd struct {
// contains filtered or unexported fields
}
Etcd implements Store
func (*Etcd) AtomicDelete ¶
func (s *Etcd) AtomicDelete(ctx context.Context, key string, previous *store.KVPair) (bool, *store.KVPair, error)
AtomicDelete 删除该键的值,如果这个键被同时修改,抛出一个错误
func (*Etcd) AtomicPut ¶
func (s *Etcd) AtomicPut(ctx context.Context, key string, value []byte, previous *store.KVPair, opts *store.WriteOptions) (bool, *store.KVPair, error)
AtomicPut 更新一个值在“键”,如果被键同时修改,则抛出错误 如果操作失败,它将返回(false, previous, error (if err != nil)) 如果操作成功,它将返回(true, nil, nil)
func (*Etcd) DeleteTree ¶
DeleteTree 产出directory下所有的键值
