pub static UNFULFILLED_LINT_EXPECTATIONS: &Lint
Expand description

The unfulfilled_lint_expectations lint detects lint trigger expectations that have not been fulfilled.

Example

#![feature(lint_reasons)]

#[expect(unused_variables)]
let x = 10;
println!("{}", x);

{{produces}}

Explanation

It was expected that the marked code would emit a lint. This expectation has not been fulfilled.

The expect attribute can be removed if this is intended behavior otherwise it should be investigated why the expected lint is no longer issued.

Part of RFC 2383. The progress is being tracked in #54503
