Lint Groups

rustc has the concept of a "lint group", where you can toggle several warnings through one name.

For example, the nonstandard-style lint sets non-camel-case-types, non-snake-case, and non-upper-case-globals all at once. So these are equivalent:

$ rustc -D nonstandard-style
$ rustc -D non-camel-case-types -D non-snake-case -D non-upper-case-globals

Here's a list of each lint group, and the lints that they are made up of:

{{groups-table}}

Additionally, there's a bad-style lint group that's a deprecated alias for nonstandard-style.

Finally, you can also see the table above by invoking rustc -W help. This will give you the exact values for the specific compiler you have installed.
