The Achilles heel of the BEAM is that if it crashes in native code then it has no way to recover and its much vaunted robustness goes out the window. So writing native hooks in Rust makes it a bit harder to crash the whole VM.

On the plus side it makes IPC pretty straightforward, so you can move the processes that need the native code (NIFs) to a separate VM if you’re feeling paranoid.

Rustler actually wraps the NIF and passes the exception back to the caller

> The library provides facilities for generating the boilerplate for interacting with the BEAM, handles encoding and decoding of Erlang terms, and catches rust panics before they unwind into C.
