使用cargo edit管理Rust项目的依赖
介绍
大概因为IDE还不够智能&强大，在Rust中每次需要引入依赖时,都需要手工添加到Cargo.toml文件中,而且版本号还要去crates上面去查 (这个通过安装插件，可以给出提示版本)
而cargo-edit可以自动帮助添加依赖,且自动更新版本号
cargo-edit[1]是一个很好用的工具，扩展了Cargo的功能，允许通过命令行修改Cargo.toml文件来添加、移除和升级依赖。
cargo-edit包括几个子命令，如cargo upgrade、cargo add和cargo rm等。
其中，cargo add，cargo rm已经在最新的cargo中集成。
cargo upgrade用于将Cargo.toml中的依赖升级到其最新版本，并提供了不同的升级选项。
cargo set-version用于在Cargo.toml中设置版本号，可以通过指定版本号或自动增加主版本、次版本或修订版本来使用。
如果没有安装cargo-edit，可以通过cargo install cargo-edit 进行安装
如果有如下报错:
error: linking with `cc` failed: exit status: 1

error: could not compile `cargo-edit` (bin "cargo-upgrade") due to previous error
error: failed to compile `cargo-edit v0.12.2`, intermediate artifacts can be found at `/var/folders/9t/839s3jmj73bcgyp5x_xh3gw00000gn/T/cargo-installhdtjjF`.
To reuse those artifacts with a future compilation, set the environment variable `CARGO_TARGET_DIR` to that path.
可应该是arm64上特有的问题，可按照 error: linking with `cc` failed: exit code: 1[2]来操作,
即在~/.cargo/config 中(如果没有此文件，则创建),增加如下内容:
[target.x86_64-apple-darwin]
rustflags = [
"-C", "link-arg=-undefined",
"-C", "link-arg=dynamic_lookup",
]
[target.aarch64-apple-darwin]
rustflags = [
"-C", "link-arg=-undefined",
"-C", "link-arg=dynamic_lookup",
]
再次cargo install cargo-edit,成功安装
使用
以添加某个crate为例：
cargo add 需要的库名
再如
