| # Suppress Rules: | |
| # - v530: The return value of function 'release_value' is required to be utilized. | |
| # Our TRY(..) macro seems to breaks this rule and trigger weird behavior in PVS Studio. | |
| # | |
| # - v677: Custom declaration of a standard '<example>' type. The declaration from system header files should be used instead. | |
| # This rule doesn't make sense for Serenity, as we are the system headers. | |
| # | |
| # - v1061: Extending the 'std' namespace may result in undefined behavior. | |
| # We have no choice, some features of C++ require us to. | |
| # | |
| # - V1052: Declaring virtual methods in a class marked as 'final' is pointless. | |
| # This rule contradicts the serenity style rules. | |
| # | |
| # - False Positives: | |
| # v591: Non-void function should return a value. | |
| # v603: Object was created but is not being used. | |
| # v1047: Lifetime of the lambda is greater than lifetime of the local variable captured by reference. | |
| # v1076: Code contains invisible characters that may alter its logic. | |
