dust: init at 0.2.3

[infinisil]

Motivation for this change

Recently having been featured on lobste.rs frontpage I was motivated to add dust to nixpkgs. It's a very simple CLI that outputs disk usage for a directory like this:

djin:git/dust> dust
  65M  .
  65M └─┬ ./target
  49M   ├─┬ ./target/debug
  26M   │ ├─┬ ./target/debug/deps
  21M   │ │ └── ./target/debug/deps/libclap-9e6625ac8ff074ad.rlib
  13M   │ ├── ./target/debug/dust
 8.9M   │ └─┬ ./target/debug/incremental
 6.7M   │   ├─┬ ./target/debug/incremental/dust-2748eiei2tcnp
 6.7M   │   │ └─┬ ./target/debug/incremental/dust-2748eiei2tcnp/s-ezd6jnik5u-163pyem-1aab9ncf5glum

 2.2M   │   └─┬ ./target/debug/incremental/dust-1dlon65p8m3vl
 2.2M   │     └── ./target/debug/incremental/dust-1dlon65p8m3vl/s-ezd6jncecv-1xsnfd0-4dw9l1r2th2t
  15M   └─┬ ./target/release
 9.2M     ├─┬ ./target/release/deps
 6.7M     │ └── ./target/release/deps/libclap-87bc2534ea57f044.rlib
 5.9M     └── ./target/release/dust

Since like on crates.io, the name dust is already taken in nixpkgs, I'm using du-dust as the package attribute instead, as is also the case for dust's 0.2.3 release.

Things done

• Built on platform(s)
  • NixOS
  • macOS
  • other Linux distributions
• Tested via one or more NixOS test(s) if existing and applicable for the change (look inside nixos/tests)
• Tested compilation of all pkgs that depend on this change using nix-shell -p nox --run "nox-review wip"
• Tested execution of all binary files (usually in ./result/bin/)
• Fits CONTRIBUTING.md.

a) For `nixos-rebuild` you can set
  { nixpkgs.config.allowUnsupportedSystem = true; }
in configuration.nix to override this.

b) For `nix-env`, `nix-build`, `nix-shell` or any other Nix command you can add
  { allowUnsupportedSystem = true; }
to ~/.config/nixpkgs/config.nix.

Fwiw tree --du or so produces something similar. But that doesn't mean dust isn't welcome!
