Hey there! I was hacking on a little Rust project on a plane last week, and I had such a great experience with the crate ecosystem around debugging tools that I raved to my colleagues about it and there was a lot of interest in this space. I thought it'd be nice to have some sort of special interest group around debugging tools to collect a list of useful crates and tools, and give people a place to discuss the topic.
As a start I've created a #rust-debugger-tools channel on irc.mozilla.org, you're welcome to join if this interests you! I chose the name arbitrarily, I couldn't come up with a better name for "the sorts of tasks that debuggers tend to do", like parsing binary formats and debug info. I'm certainly open to suggestions!
Specifically for my rust-disasm tool I found that just plugging together gimli's addr2line and object (which is a layer atop goblin) crates, as well as the capstone crate for disassembling instructions got me a long way towards what I wanted to do, and I didn't feel like I had to write any really hard code, which was awesome!
Thanks!
