*Note:* This post describes panicking as of [this commit](https://github.com/rust-lang/rust/commit/4007d4ef26eab44bdabc2b7574d032152264d3ad).
Many of the interfaces described here are unstable internal details of libstd, and subject to change any time.
+*Update (2025-08-18):* As expected, many parts of this post are quite outdated by now.
+See [here](https://github.com/rust-lang/rust/issues/116005) for an issue tracking the ongoing cleanup effort of the panic machinery.
