使用 nightly 版本时，Crates 源可能会出现 Couldn't resolve host name (Could not resolve host: crates) 错误（见 #294）。一个临时的解决方法是在运行 cargo 的时候加入环境变量 CARGO_HTTP_MULTIPLEXING=false。

设置后能否正常下载？

使用这个方法能解决，但是我用的是stable branch

[name@manjaro ~]$ rustc --version
rustc 1.60.0 (7737e0b5c 2022-04-04)
[name@manjaro ~]$ cargo --version
cargo 1.60.0 (d1fd9fe 2022-03-01)

目前的配置是 crates 反代允许 20r/s 的频率访问，我猜测 cargo 可能没有限制并发数量导致超过了这个限制，并且相关的代码已经进入了稳定版。

移至 #294 讨论。
