The library's from_json() overloads (containers, maps, std::array, C arrays, pairs, tuples, optional, valarray, forward_list, enums, binary, paths, and scalars) accept views: their traits use the view's basic_json type, and the few accesses that differ (get_ptr) go through small helpers. from_json() of a view now finds them; only the probe still looks up by ADL only. get<T>() of a view thus converts these types without materialize(), with the same values and exceptions; from an object, a repeated key keeps the last value, as parse() does. The view keeps its direct paths for vectors of the types it converts directly (faster than from_json()) and for containers of views; its other vector and map paths are replaced by from_json(). For basic_json, std::valarray and std::forward_list are read in one pass (40 % and 3.5 % fewer instructions); all other conversions are unchanged. Signed-off-by: Niels Lohmann <mail@nlohmann.me>
