rustc 有一个“lint 组”的概念，您可以通过一个名称切换多个警告。
例如，nonstandard-style lint 会一次性设置 non-camel-case-types、non-snake-case 和 non-upper-case-globals。 因此，以下是等效的：
$ 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 组的列表，以及它们包含的 lint：
| 组 | 描述 | Lint |

| rust-2018-idioms | 引导您使用 Rust 2018 的惯用功能的 Lint | bare-trait-objects, elided-lifetimes-in-paths, ellipsis-inclusive-range-patterns, explicit-outlives-requirements, unused-extern-crates |

此外，还有一个 bad-style lint 组，它是 nonstandard-style 的已弃用别名。
最后，您还可以通过调用 rustc -W help 来查看上表。 这将为您提供已安装的特定编译器的确切值。
