It's also worth noting that Rust does also have stack-unwinding error propagation, in the form of `panic`/`catch_unwind`, which can be used as a less-ergonomic optimization in situations like this. Result types like this also don't color the function, since you can just explicitly panic, which would be inlined at the call site and show similar performance to C++ exceptions.

This is very much non-idiomatic. Panics are not intended as “application” error reporting, but rather as “programming” error.

The intended use-case of catch_unwind is to protect the wider program e.g. avoid breaking a threadpool worker or a scheduler on panic, or transmit the information cross threads or to collation tools like sentry.
