Types

type Tags

type Tags interface {
	// Set sets the given key in the metadata tags.
	Set(key string, value interface{}) Tags
	// Has checks if the given key exists.
	Has(key string) bool
	// Values returns a map of key to values.
	// Do not modify the underlying map, please use Set instead.
	Values() map[string]interface{}
}

Tags is the interface used for storing request tags between Context calls. The default implementation is *not* thread safe, and should be handled only in the context of the request.

func Extract

func Extract(ctx context.Context) Tags

Extracts returns a pre-existing Tags object in the Context. If the context wasn't set in a tag interceptor, a no-op Tag storage is returned that will *not* be propagated in context.

func NewTags

func NewTags() Tags
