## プロジェクトの歴史と使われ方

zet is a focused Rust command-line tool for treating files as sets of lines and computing union, intersection, difference, single-occurrence, and multiple-occurrence results while removing duplicates.

### プロジェクトの歴史

The public trail is mostly the repository and a July 2021 Rust Users Forum announcement. The author positioned zet as a small Unix-style utility comparable to uniq and comm, but aimed at direct set operations over whole files rather than sorted-stream workflows.

### 使われ方

Users run commands such as zet union, zet intersect, and zet diff over two or more input files. The README emphasizes that output preserves the order in which lines first appear, while the forum announcement notes details such as UTF-16 handling, BOM behavior, line-ending normalization, and memory use proportional to the largest argument plus output.

### パッケージ好きにとっての重要性

zet is a nice package-catalog specimen because it fills a tiny gap left by classic POSIX text tools: set algebra over lines without forcing the user to pre-sort files or compose a longer shell pipeline.

### タイムライン

- 2021-07-05: zet is announced on the Rust Users Forum as a CLI for set operations on files considered as sets of lines.

### Related projects

- uniq and comm are the traditional Unix comparison points named by the project README.
- setutils is a broader family of command-line set-operation utilities in a similar niche.
