在「Arti 1.0.0 is released: Our Rust Tor implementation is ready for production use.」這邊看到 Tor 的 Rust 計畫進入了 1.0.0 版。
不過每次編 Rust 的東西都會發現 Rust 版本不夠新，這次也不例外，就不知道是 Rust community 的特性還是真的太少用 Rust...
Updating crates.io index
Downloaded arti v1.0.0
error: failed to parse manifest at `/home/gslin/.cargo/registry/src/github.com-1ecc6299db9ec823/arti-1.0.0/Cargo.toml`
Caused by:
feature `edition2021` is required
this Cargo does not support nightly features, but if you
switch to nightly channel you can add
`cargo-features = ["edition2021"]` to enable this feature
用 rustup update 更新後就能編了，然後跑起來看起來沒什麼問題：

用 curl 測試也的確是 Tor 的 exit node 了：
$ curl -i --socks5 127.0.0.1:9150 https://httpbin.org/ip
HTTP/2 200

}
$ host 85.93.218.204

看起來 client 的功能能用了...
