pretty printing rust with rr

using rust pretty printers with rr

rr is a great debugging tool. it records a trace of a program's execution, as well as the results of any syscalls it executes, so that you can "rewind" while you debug, and get deterministic forward and reverse instrumented playback. it works with rust, but by default if you try it out, it could be pretty ugly when you inspect variables.



  1. get the rust pretty printer python script
  2. configure gdb to automatically load it


import sys  

# set this to the path of the pretty printer
sys.path.insert(0, '/path/to/src/rust/src/etc/')

import gdb_rust_pretty_printing
