[INFO] [stdout]     = note: packed structs are only aligned by one byte, and many modern architectures penalize unaligned field accesses
[INFO] [stdout]     = note: creating a misaligned reference is undefined behavior (even if that reference is never dereferenced)
[INFO] [stdout]     = help: copy the field contents to a local variable, or replace the reference with a raw pointer and use `read_unaligned`/`write_unaligned` (loads and stores via `*p` must be properly aligned even when using raw pointers)
[INFO] [stdout]     = note: this error originates in the macro `$crate::__export::format_args` which comes from the expansion of the macro `format` (in Nightly builds, run with -Z macro-backtrace for more info)
