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: pub_use.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 rustc_ast::ast::{Item, ItemKind, VisibilityKind};
use rustc_lint::{EarlyContext, EarlyLintPass};
use rustc_session
    
    fn check_item(&mut self, cx: &EarlyContext<'_>, item: &Item) {
        if let ItemKind::Use(_) = item.kind
            && let VisibilityKind::Public = item.vis.kind
        {
            span_lint_and_help(
                cx,
                PUB_USE,
                item.span,
                "using `pub use`",
                None,
                "move the exported item to a public module instead",
            );
        }
    }
