SUMMARY

Hi I couldn't find a separate location to file feature requests so I hope this it the right location. Currently when looking at Rust binaries I get some partially demangled names. Presumably it is close enough to C++ to get some demangling. Unfortunately that is probably the worst option, as I can't just copy paste the half-demangled name into a proper rust demangler (like https://github.com/luser/rustfilt).

I would thus appreciate if you either didn't demangle rust symbols at all, or used https://github.com/rust-lang/rustc-demangle#usage-from-non-rust-languages to do it fully. I know that hotspot by KDAB (which seems very closely related to this GUI-wise) already has support for rust demangling, so maybe it wouldn't be too difficult to add here as well.

STEPS TO REPRODUCE
1.  Profile a rust binary
2. Open in heaptrack_gui
3. Be met with confusing partially demangled names

OBSERVED RESULT
Partially demangled names

EXPECTED RESULT
Preferably fully demangled (otherwise not demangled at all)
