当 运行 in GitHub Actions 时，Cargo 无法下载依赖项
Cargo fails to download dependencies when running in GitHub Actions
当 cargo check 运行 在 GitHub 操作中时，它会下载大部分依赖项，但偶尔会在其中一个上失败。它在每个 运行 上都失败了（我测试了大约 5 次）。
下载依赖项在本地有效。

Caused by:
[55] Failed sending data to the peer (Connection died, tried 5 times before giving up)
Error: The process '/usr/share/rust/.cargo/bin/cargo' failed with exit code 101
这是什么原因造成的？
似乎是 nightly 工具链的问题。
将 toochain: nightly 更改为 toolchain: nightly-2021-07-05
在 ci 文件中解决了它：
uses: actions-rs/toolchain@v1
with:
profile: minimal
toolchain: nightly-2021-07-05
override: true
components: rustfmt
