Bug ID: 481485
Summary: [Feature request] Add support for rust demangling
(using rustc-demangle C library probably)
Classification: Applications
Product: Heaptrack
Version: 1.5.0
Platform: Arch Linux
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: general
Assignee: m...@milianw.de
Reporter: kdeb...@vorpal.se
Target Milestone: ---
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)
