Overview

    Package memcache provides functions to trace the bradfitz/gomemcache package (https://github.com/bradfitz/gomemcache).

    `WrapClient` will wrap a memcache `Client` and return a new struct with all the same methods, so should be seamless for existing applications. It also has an additional `WithContext` method which can be used to connect a span to an existing trace.

            CompareAndSwap invokes and traces Client.CompareAndSwap.

            func (*Client) Decrement

            func (c *Client) Decrement(key string, delta uint64) (newValue uint64, err error)

              Decrement invokes and traces Client.Decrement.

              func (*Client) Delete

              func (c *Client) Delete(key string) error

                Delete invokes and traces Client.Delete.

                func (c *Client) DeleteAll() error

                  DeleteAll invokes and traces Client.DeleteAll.

                  func (*Client) FlushAll

                  func (c *Client) FlushAll() error

                    FlushAll invokes and traces Client.FlushAll.

                    func (*Client) Get

                    func (c *Client) Get(key string) (item *memcache.Item, err error)

                      Get invokes and traces Client.Get.

                      func (*Client) GetMulti

                      func (c *Client) GetMulti(keys []string) (map[string]*memcache.Item, error)

                        GetMulti invokes and traces Client.GetMulti.

                        func (*Client) Increment

                        func (c *Client) Increment(key string, delta uint64) (newValue uint64, err error)

                          Increment invokes and traces Client.Increment.

                          func (*Client) Replace

                          func (c *Client) Replace(item *memcache.Item) error

                            Replace invokes and traces Client.Replace.

                            func (*Client) Set

                            func (c *Client) Set(item *memcache.Item) error

                              Set invokes and traces Client.Set.
