• based on diff against files which were unmodified since last cargo ll*?
  • if we rerun cargo ll* during working on compiler messages — still we need to do precise jumps
    • make snapshot of affected files from g:CargoLimitOpen?
      • nope, we may continue editing files while cargo ll* hasn't finished yet
    • make copy of all opened nvim buffers just before starting cargo ll*?
      • requires additional API
      • still we may modify something that hasn't been processed by compiler yet
      • ideally we need exact files that were processed by compiler
        • wrap rustc with "copy the source + run rustc" script?
          • RUSTC_WRAPPER? CARGO_BUILD_RUSTC_WORKSPACE_WRAPPER?
            • user may want to overwrite it with something like sccache, we need to wrap what they wrapped
• seems to be working, still needs some debugging/testing
• quickfix list supports such lines positions tracking?
  • reimplement based on the quickfix list?
