twiggy is a code size profiler.
It analyzes a binary's call graph to answer questions like:
Why was this function included in the binary in the first place?
What is the retained size of this function? I.e. how much space would be saved if I removed it and all the functions that become dead code after its removal.
twiggy to make your binaries slim!
Ensure that you have the Rust toolchain installed, then run:
cargo install twiggy
