0.8.0

• Generate // TODO: comments after panics.
• Style changes to ./middleware/logging.go, ./endpoints.go and ./exchanges.go.
• Add generation of opentracing #53 :
  • Serves server and client side by wrapping endpoints.
  • Passes spans to headers/meta for http and grpc transports.
• Add cache middleware #54 :
  • Generates Cache interface:

  type Cache interface {
      Set(key, value interface{}) (err error)
      Get(key interface{}) (value interface{}, err error)
  }

  • Service methods will use first argument as key and all results as value.
  • Or you may add code, which will replace 'key'.
    // @cache-key createdAt.UTC()
  • Useful on client and server sides.
  • You should write your own, or adapt existing storage (e.g. sync.Map).

  type InMemoryCache struct {
  	sync.Map
  }
  
  func (c *InMemoryCache) Set(key, value interface{}) error {
  	c.Store(key, value)
  	return nil
  }
  
  func (c *InMemoryCache) Get(key interface{}) (interface{}, error) {
  	value, _ := c.Load(key) // remember about _
  	return value, nil
  }
