Is there a convenient way to get a heap profile in Rust? I'd expect it shouldn't be too hard. I'm used to using pprof with tcmalloc, jemalloc is based on tcmalloc, and Rust uses jemalloc by default. pprof heap profiles make this kind of thing easy to debug. It draws a call graph using graphviz. Boxes are scaled according the total byte size, so if there's a large leak you can pull up the graph and the giant box all but says "you idiot, the problem is right here".
