Phobos(和/或Tango)有一组预定义的异常类型吗？

Question

D文档似乎有点乱,我无法在官方网站上的任何地方找到这些信息.我需要一些常见的异常类型(例如NotFiniteNumberException,FileIOException,类似的类型),这些存在于核心库中,还是我必须自己滚动？

Answer 1

其中一些存在,其中一些不存在.找到它们的最佳策略是: Exception在D运行时(和Phobos)中进行全局搜索查找文本,并查看所有预先存在的异常.

但是,最有可能的是,你必须推出至少一些你自己的.

我通过此搜索找到的内容如下:

(当然,如果有异常继承自类以外的类Exception,或者如果间距很奇怪,则它们不在此列表中.)
