-/// The entry point for panic of Rust threads.
-///
-/// This macro is used to inject panic into a Rust thread, causing the thread to
-/// unwind and panic entirely. Each thread's panic can be reaped as the
-/// `Box<Any>` type, and the single-argument form of the `panic!` macro will be
-/// the value which is transmitted.
-///
-/// The multi-argument form of this macro panics with a string and has the
-/// `format!` syntax for building a string.
-///
-/// # Examples
-///
-/// ```should_panic
-/// # #![allow(unreachable_code)]
-/// panic!();
-/// panic!("this is a terrible mistake!");
-/// panic!(4); // panic with the value of 4 to be collected elsewhere
-/// panic!("this is a {} {message}", "fancy", message = "message");
-/// ```
