Member Function Documentation
◆ check_non_overlapping_cases()
| bool if_chain::check_non_overlapping_cases | ( | ) |
Verify that all case ranges do not overlap.

◆ is_beneficial()
| bool if_chain::is_beneficial | ( | ) |
Return true when the switch can be expanded with a jump table or a bit test (at least partially).
