This extends the `panic_fmt` lint to warn for all cases where the first argument cannot be interpreted as a format string, as will happen in Rust 2021. It suggests to add `"{}", ` to format the message as a string. In the case of `std::panic!()`, it also suggests the recently stabilized `std::panic::panic_any()` function as an alternative. It renames the lint to `non_fmt_panic` to match the lint naming guidelines. |
