如何在 Nim 中禁用警告
How to disable warning in Nim
我正在尝试抑制此警告:
Warning: inherit from a more precise exception type like ValueError, IOError or OSError. If these don't suit, inherit from CatchableError or Defect. [InheritFromException]
我试过这个:
type
ReturnException* = ref object of Exception {.warning[InheritFromException]:off.}
value*: BaseType
warning pragma 是一个打开和关闭的开关。所以你需要做这样的事情:
{.warning[InheritFromException]:off.}
type
ReturnException* = ref object of Exception
value*: BaseType
{.warning[InheritFromException]:on.}
使用这个:
type
ReturnException* = ref object of CatchableError
或:
type
ReturnException* = ref object of Defect
区别在于CatchableException
可以被try/except
捕获,而Defect
总是导致程序退出。
