rustc 有“lint 分组”的概念，你可以通过一个名称来切换多个警告。
例如，nonstandard-style lint 会同时设置 non-camel-case-types、non-snake-case 和 non-upper-case-globals。所以这些是等效的
$ rustc -D nonstandard-style
$ rustc -D non-camel-case-types -D non-snake-case -D non-upper-case-globals
以下是每个 lint 分组及其包含的 lint 列表

此外，还有一个 bad-style lint 分组，它是 nonstandard-style 的已弃用别名。
最后，你也可以通过执行 rustc -W help 查看上述表格。这将提供你安装的特定编译器版本的确切值。
