You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: missing_assert_message.rs
    path of file: ./repos/rust-clippy/clippy_lints/src
    
    the code of the file until where you have to start completion: use clippy_utils::diagnostics::span_lint_and_help;
use clippy_utils::macros::{find_assert_args, find_assert_eq_args, root_macro_call_first_node, PanicExpn};
use clippy_utils::{is_in_cfg_test, is_in_test_function};
use rustc_hir::Expr;
use rustc_lint::{LateContext, LateLintPass};
use rustc_session::declare_lint_pass;
use rustc_span::sym;
    
    fn check_expr(&mut self, cx: &LateContext<'tcx>, expr: &'tcx Expr<'_>) {
        let Some(macro_call) = root_macro_call_first_node(cx, expr) else {
            return;
        };
        let single_argument = match cx.tcx.get_diagnostic_name(macro_call.def_id) {
            Some(sym::assert_macro | sym::debug_assert_macro) => true,
            Some(
                sym::assert_eq_macro | sym::assert_ne_macro | sym::debug_assert_eq_macro | sym::debug_assert_ne_macro,
            ) => false,
            _ => return,
        };

        // This lint would be very noisy in tests, so just ignore if we're in test context
        if is_in_test_function(cx.tcx, expr.hir_id) || is_in_cfg_test(cx.tcx, expr.hir_id) {
            return;
        }

        let panic_expn = if single_argument {
            let Some((_, panic_expn)) = find_assert_args(cx, expr, macro_call.expn) else {
                return;

                MISSING_ASSERT_MESSAGE,
                macro_call.span,
                "assert without any message",
                None,
