// 1. Define you input struct
type ListUsersInput struct {
	Page     int  `in:"form=page"`
	PerPage  int  `in:"form=per_page"`
	IsMember bool `in:"form=is_member"`
}

// 2. Bind this input struct with an HTTP handler
func init() {
	http.Handle("/users", alice.New(
		httpin.NewInput(ListUsersInput{}),
	).ThenFunc(ListUsers))
}

// 3. Use the input in the handler, all the parsing stuff are handled by httpin
func ListUsers(rw http.ResponseWriter, r *http.Request) {
	input := r.Context().Value(httpin.Input).(*ListUsersInput)
}
