Hello,
I've been tackling with profiling Rust Analyzer and found that I can't view a flamegraph, because of its size. Viewing the generatetd SVG in any browser was implosible. In fact, it was simply frozen despite my pretty good machine. Therefore, I implemented a viewer of flamegraphs with Rust and Xlib. Also, I've added fuzzy search with Dmenu. The link to the project. Also, I came across a few challenges and wrote a little article about it.
