%% `all' must request and return all flags and segments, along with an updated

%% state value. It takes the destination URI, the SDK key, along with a state

%% value from `init' or the previous invocation of `all' to allow for features

%% such as ETag caching.

-callback all(Uri :: string(), State :: any()) -> {response(), any()}.



%% `init' should return an initial value for the `State' argument to `all'

-callback init(Tag :: atom(), SdkKey :: string()) -> any().
