[INFO] [stdout]     = note: the assert!() macro supports formatting, so there's no need for the format!() macro here
[INFO] [stdout]     = note: this warning originates in the macro `parses_to` (in Nightly builds, run with -Z macro-backtrace for more info)
[INFO] [stdout] help: remove the `format!(..)` macro call
