Crate dfrs 

dfrs is a terminal-only filesystem usage viewer.

The executable follows a small pipeline: parse the CLI, discover mounts through the platform provider, collect statfs counters, apply the df-like visibility policy, and render the selected columns. The crate is a binary rather than a reusable library, so these RustDoc comments describe CLI behavior and implementation seams for maintainers and downstream packagers.
