Should init/2 return {ok, ...} or ignore?

[therealcarloratm]

Just a question, I am not an expert.

I see here the typespec says init/2 should return {ok, standard} or {ok, handover}:

elli/src/elli_handler.erl

Line 43 in c874c42

-callback init(Req, Args) -> {ok, standard | handover} when

While here it mentions ignore as a return value:

elli/src/elli_example_callback_handover.erl

Line 8 in c874c42

%% otherwise `ignore'.

What's the correct one?

Cheers

Yup, and if you look in elli_http and elli_middleware it handles ignore as a return from init.

[therealcarloratm]

So the callback should be defined as:

-callback init(Req, Args) -> {ok, standard | handover} | ignore when

?

Yea.
