Description
Once rust-lang/rust#65193 (hopefully) lands, future compatibility lints will have a slightly new registration format:
A @future_incompatible "field" is used in the declare_lint macro, e.g.,
declare_lint! {
pub DUPLICATE_MACRO_EXPORTS,
Deny,
"detects duplicate macro exports"
@future_incompatible = FutureIncompatibleInfo {
reference: "issue #35896 <https://github.com/rust-lang/rust/issues/35896>",
edition: Some(Edition::Edition2018),
},
}We will also want to include this comment somehow:
// Guidelines for creating a future incompatibility lint:
//
// - Create a lint defaulting to warn as normal, with ideally the same error
// message you would normally give
// - Add a suitable reference, typically an RFC or tracking issue. Go ahead
// and include the full URL, sort items in ascending order of issue numbers.
// - Later, change lint to error
// - Eventually, remove lint
