cargo-limit⮳ is Cargo with less noise: warnings are skipped until errors are fixed, Neovim integration, etc.

  • errors have highest priority
  • they never appear in the middle of warnings
  • warnings are skipped by default until errors are fixed
  • external path dependencies' warnings are skipped by default
  • all messages come in reversed order by default to avoid extra scrolling
  • messages are grouped by filenames
  • number of messages can be limited
  • after encountering first error the rest of build time is limited by default
  • files can be automatically opened in your text editor on affected lines

This tool is especially useful in combination with cargo-watch.
