How to make beautiful call graphs for Rust
Raw
how-to-make-beautiful-call-graphs-for-rust.md

I found the instructions in this reddit comment by the user fn_rust. Dependencies:

The instructions are illustrated on the rb crate:

  1. Build a binary with debug symbols (no --release flag was given): cargo build --example saw
  2. Run it with valgrind: valgrind --tool=callgrind --dump-instr=yes --collect-jumps=yes --simulate-cache=yes ./target/debug/examples/saw
  3. Convert the graph into a png: gprof2dot --format=callgrind callgrind.out.9815 | dot -o callgrind-graph.png -Tpng
  4. Done!
