 # A subset of `rustc` lints that are allowed by default.
 # A few notable ones that we do not enable:
 #
-# - `variant_size_differences`
-#   `clippy::large_enum_variant` does nearly the same thing and is enabled by default.
+# - `elided_lifetimes_in_paths`
+#   It hurts readability and doesn't provide a clear benefit.
+#
+# - `keyword_idents_2024`
+#   Starting with Rust 1.79.0, uses of `rand::Rng::gen` trigger `keyword_idents_2024`.
+#   `rand` has renamed the method to `random`, but the change has not been released. See:
+#   - <https://github.com/rust-random/rand/issues/1435>
+#   - <https://github.com/rust-random/rand/pull/1438>
 #
 # - `missing_copy_implementations`
 #   This would be more useful if it only triggered for types that are `Clone` but not `Copy`.

-# - `elided_lifetimes_in_paths`
-#   It hurts readability and doesn't provide a clear benefit.
