For earlier discussion, see https://github.com/rust-lang/rust/issues/11695
This issue was labelled with: in the Rust repository
I can't always guarantee that users are going to properly use a library (calling init methods, cleanup methods, etc.).
Occasionally things die horribly and you want to provide stronger guarantees about when things fail.
Is there a way to hook up to an exit signal of sorts to execute code when a program exits regardless of the exit mechanism? Something like Python atexit?
