介绍


大略因为IDE还不够智能&弱小，在Rust中每次须要引入依赖时,都须要手工增加到Cargo.toml文件中,而且版本号还要去crates下面去查 (这个通过装置插件，能够给出提醒版本)

而cargo-edit能够主动帮忙增加依赖,且自动更新版本号

cargo-edit是一个很好用的工具，扩大了Cargo的性能，容许通过命令行批改Cargo.toml文件来增加、移除和降级依赖。

cargo-edit包含几个子命令，如cargo upgrade、cargo add和cargo rm等。

其中，cargo add，cargo rm曾经在最新的cargo中集成。

cargo upgrade用于将Cargo.toml中的依赖降级到其最新版本，并提供了不同的降级选项。

cargo set-version用于在Cargo.toml中设置版本号，能够通过指定版本号或主动减少主版本、次版本或修订版原本应用。


如果没有装置cargo-edit，能够通过cargo install cargo-edit 进行装置

如果有如下报错:

可应该是arm64上特有的问题，可依照 cc failed: exit code: 1">error: linking with cc failed: exit code: 1来操作,

即在~/.cargo/config 中(如果没有此文件，则创立),减少如下内容:

[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,胜利装置


应用


以增加某个crate为例：

cargo add 须要的库名
