[INFO] [stderr]    = note: this usage of `panic!()` is deprecated; it will be a hard error in Rust 2021
[INFO] [stderr]    = note: for more information, see <https://doc.rust-lang.org/nightly/edition-guide/rust-2021/panic-macro-consistency.html>
[INFO] [stderr]    = note: the `panic!()` macro supports formatting, so there's no need for the `format!()` macro here
[INFO] [stderr] help: remove the `format!(..)` macro call
