pub unsafe fn at_binary_exit(cb: extern "C" fn())Expand description
Registers a raw function to be called at binary exit time.
Corresponds to atexit in C.
Unsupported on Windows platforms: the platform’s libc atexit tracks a set
of functions per module.
§Safety
Rust does not provide any safety guarantees about life-before-main or life-after-main. Ordering of destructors is not guaranteed, nor that a destructor will be called at all.
