A minimalist df clone written in Rust — displays mounted filesystems, disk usage, and colored usage bars in a clean column layout.

• Parses /proc/mounts directly — no shelling out or external binaries
• Uses libc::statvfs for disk statistics (no extra crates)
• Filters out pseudo-filesystems (proc, tmpfs, sysfs, etc.)
• Displays:
  • Filesystem device
  • Total, used, available space
  • Usage percentage
  • Colored bar graph (■) indicating usage level
• ANSI color output with clear thresholds:
  • Green: < 75%
  • Yellow: 75–85%
  • Red: > 85%
