  • Using the PanicFmt derive macro (requires the opt-in "derive" feature)
  • Using the impl_panicfmt macro (requires the default-enabled "non_basic" feature)
  • Using the flatten_panicvals macro (requires the default-enabled "non_basic" feature)
  • Manually implementing the PanicFmt trait as described in its docs.
