This is great. I've wanted to start a project in Rust but I'm hesitant since I haven't found any profiling tools akin to VisualVM. I'd feel a bit blind writing multi-threaded code where I can't see what's going on. What do people use to sanity check this sort of thing?

One nice aspect is that Rust gives you many kinds of threading errors at compile time, so that helps. :)

Any profiling tool that works for C or C++ should work just fine for Rust. For example, people often use perf for performance work.
