Functions

func Get

func Get(r *http.Request, key interface{}) (interface{}, bool)

Get stored value inside kv

func Injector

func Injector(key interface{}, value interface{}) func(http.HandlerFunc) http.HandlerFunc

Injector return middleware to set value with the key

func MustGet

func MustGet(r *http.Request, key interface{}) interface{}

MustGet do the same thing as Get, but will panic if it never set before

func WithValue

func WithValue(r *http.Request, key interface{}, value interface{}) *http.Request

WithValue will return request that have kv instance in its context, and also set kv entry with provided key and value
