#![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

#![expect(rustdoc::missing_crate_level_docs)]
//~^ WARNING this lint expectation is unfulfilled [unfulfilled_lint_expectations]
//~| NOTE `#[warn(unfulfilled_lint_expectations)]` on by default
