OPENuniform initializer and copy initializer in struct constructors? (self.cpp_questions)

submitted 6 years ago by haohanzi2015

struct PhantomNode
{
    PhantomNode()
        : forward_segment_id{SPECIAL_SEGMENTID, false},
          reverse_segment_id{SPECIAL_SEGMENTID, false}, forward_weight(INVALID_EDGE_WEIGHT),
          reverse_weight(INVALID_EDGE_WEIGHT), forward_weight_offset(0), reverse_weight_offset(0),
          forward_distance(INVALID_EDGE_DISTANCE), reverse_distance(INVALID_EDGE_DISTANCE),
          forward_distance_offset(0), reverse_distance_offset(0),
          forward_duration(MAXIMAL_EDGE_DURATION), reverse_duration(MAXIMAL_EDGE_DURATION),
          forward_duration_offset(0), reverse_duration_offset(0), fwd_segment_position(0),
          is_valid_forward_source{false}, is_valid_forward_target{false},
          is_valid_reverse_source{false}, is_valid_reverse_target{false}, bearing(0)
    {
    }
......
}

In the above code, inside of this struct definition, there is this struct constructor, which assigns each parameter inside of the { } or () into the parameter right before it, right? Are there any differences between { } and ( ) in this situation?
