Lint Groupsrustc 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:
Group Description Lints warnings All lints that are set to issue warnings See warn-by-default for the default set of warnings deprecated-safe Lints for functions which were erroneously marked as safe in the past deprecated-safe-2024 future-incompatible Lints that detect code that has future-compatibility problems aarch64-softfloat-neon, ambiguous-associated-items, ambiguous-glob-imports, coherence-leak-check, conflicting-repr-hints, const-evaluatable-unchecked, elided-lifetimes-in-associated-constant, forbidden-lint-groups, ill-formed-attribute-input, invalid-type-param-default, late-bound-lifetime-arguments, legacy-derive-helpers, macro-expanded-macro-exports-accessed-by-absolute-paths, out-of-scope-macro-calls, patterns-in-fns-without-body, proc-macro-derive-resolution-fallback, pub-use-of-private-extern-crate, repr-transparent-external-private-fields, self-constructor-from-outer-item, semicolon-in-expressions-from-macros, soft-unstable, uncovered-param-in-projection, uninhabited-static, unstable-name-collisions, unstable-syntax-pre-expansion, unsupported-calling-conventions keyword-idents Lints that detect identifiers which will be come keywords in later editions keyword-idents-2018, keyword-idents-2024 let-underscore Lints that detect wildcard let bindings that are likely to be invalid let-underscore-drop, let-underscore-lock nonstandard-style Violation of standard naming conventions non-camel-case-types, non-snake-case, non-upper-case-globals refining-impl-trait Detects refinement ofimpl Trait return types by trait implementations refining-impl-trait-internal, refining-impl-trait-reachable rust-2018-compatibility Lints used to transition code from the 2015 edition to 2018 absolute-paths-not-starting-with-crate, anonymous-parameters, keyword-idents-2018, tyvar-behind-raw-pointer rust-2018-idioms Lints to nudge you toward idiomatic features of Rust 2018 bare-trait-objects, elided-lifetimes-in-paths, ellipsis-inclusive-range-patterns, explicit-outlives-requirements, unused-extern-crates rust-2021-compatibility Lints used to transition code from the 2018 edition to 2021 array-into-iter, bare-trait-objects, ellipsis-inclusive-range-patterns, non-fmt-panics, rust-2021-incompatible-closure-captures, rust-2021-incompatible-or-patterns, rust-2021-prefixes-incompatible-syntax, rust-2021-prelude-collisions rust-2024-compatibility Lints used to transition code from the 2021 edition to 2024 boxed-slice-into-iter, dependency-on-unit-never-type-fallback, deprecated-safe-2024, edition-2024-expr-fragment-specifier, if-let-rescope, impl-trait-overcaptures, keyword-idents-2024, missing-unsafe-on-extern, never-type-fallback-flowing-into-unsafe, rust-2024-guarded-string-incompatible-syntax, rust-2024-incompatible-pat, rust-2024-prelude-collisions, static-mut-refs, tail-expr-drop-order, unsafe-attr-outside-unsafe, unsafe-op-in-unsafe-fn unknown-or-malformed-diagnostic-attributes detects unknown or malformed diagnostic attributes malformed-diagnostic-attributes, malformed-diagnostic-format-literals, misplaced-diagnostic-attributes, unknown-diagnostic-attributes unused Lints that detect things being declared but not used, or excess syntax dead-code, map-unit-fn, path-statements, redundant-semicolons, unreachable-code, unreachable-patterns, unused-allocation, unused-assignments, unused-attributes, unused-braces, unused-doc-comments, unused-extern-crates, unused-features, unused-imports, unused-labels, unused-macro-rules, unused-macros, unused-must-use, unused-mut, unused-parens, unused-unsafe, unused-variables
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.
