cargo-limit

Cargo with less noise:

• errors have highest priority
  • they never appear in the middle of warnings
  • warnings are skipped by default until errors are fixed
  • all 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.

Why "limit"?

Initially it was just a workaround for this issue.
