I have expression `vtg_ground_speed_unit > 0 ? vtg_ground_speed_knots : vtg_ground_speed_kph`. These variables (`vtg_ground_speed_unit`, `vtg_ground_speed_knots`, `vtg_ground_speed_kph`) can only be from fixed list (coming from configuration file). So it would be nice...
functions inside expressions are evaluated in coroutine and on panic are not recovered thus crashing whole application. I think there should be somekind of recover as when coroutine ends with...
first of all, thanks for the nice project solves my problem a lot. here is one feature request after using this module in more scenarios of the projects, i'd like...
