pub fn panic_fmt(fmt: Arguments<'_>) -> !🔬This is a nightly-only experimental API. (
panic_internals)Expand description
The entry point for panicking with a formatted message.
This is designed to reduce the amount of code required at the call
site as much as possible (so that panic!() has as low an impact
on (e.g.) the inlining of other functions as possible), by moving
the actual formatting into this shared place.
