#![feature(lint_reasons)]
|
|
//! This file tests the `#[expect]` attribute implementation for tool lints. The same
|
|
//! file is used to test clippy and rustdoc. Any changes to this file should be synced
|
|
//! to the other test files as well.
|
|
//!
|
|
//! Expectations:
|
|
//! * rustc: only rustc lint expectations are emitted
|
|
//! * clippy: rustc and Clippy's expectations are emitted
|
|
//! * rustdoc: only rustdoc lint expectations are emitted
|
|
//!
|
|
//! This test can't cover every lint from Clippy, rustdoc and potentially other
|
|
//! tools that will be developed. This therefore only tests a small subset of lints
