Missing renderer for HashMaps in debugger

I'm using current nightly channel of Rust and LLDB for debugging. I've tried debugging with VS Code and CLion and I've tried LLDB and GDB. But all combinations fail to display the contents of HashMaps.
Only solution is to print the contens to stdout.
I've HashMaps like:

HashMap<String, FooStruct>
HashMap<u64, Vec<(String, usize)>>

Is it a known bug, or is there any solution available for this problem?

Sounds like it's just a feature that hasn't been implemented yet. I'd create a bug against LLDB and see how easy it is add support for printing more types.
