Struct smart_read::list_constraints::EnumerateInput

pub struct EnumerateInput<T: TryRead>(pub T);

Returns the index of the chosen item along with the item.   NOTE : If you filter the inputs before feeding them into EnumerateInput, the indices returns won’t match the indices of the initial input. In this case, you might want to use OptionWithData instead
