// rust crate.

// See the corresponding assembly code for this file (as compiled on Linux with g++ 11.4.0) in
// `a.s`. To experiment with the demangling feature, in your editor hover over a label, like
// `_ZnwmPv` and see what's the corresponding C++ function / definition (should show
// `operator new(unsigned long, void*)`)
