pub static FORBIDDEN_LINT_GROUPS: &Lint
Expand description
The forbidden_lint_groups
lint detects violations of
forbid
applied to a lint group. Due to a bug in the compiler,
these used to be overlooked entirely. They now generate a warning.
§Example
#![forbid(warnings)]
#![deny(bad_style)]
fn main() {}
{{produces}}
§Recommended fix
If your crate is using #![forbid(warnings)]
,
we recommend that you change to #![deny(warnings)]
.
§Explanation
Due to a compiler bug, applying forbid
to lint groups
previously had no effect. The bug is now fixed but instead of
enforcing forbid
we issue this future-compatibility warning
to avoid breaking existing crates.
