cargo 解决git依赖私库办法

Rust实际场景，不仅需要依赖https://crates.io/的公共mod，自己依赖的git私库服务也是常见现象。
cargo正好也解决了私库依赖的问题。详细说明见链接：

cargo git私库解决办法

• 1. 添加.ssh/config配置

Host *
   UseKeychain yes
   AddKeysToAgent yes
   IdentityFile ~/.ssh/id_rsa

• 2. 指定私钥文件

ssh-add -K ~/.ssh/id_rsa

• 3. cargo 的toml文件添加依赖，如下

[package]
name = "demo_rust"
version = "0.1.0"
authors = ["baoyachi "]
edition = "2018"

# See more keys and their definitions at https://doc.rust-lang.org/cargo/reference/manifest.html

[dependencies]
json               = "0.4"
pretty_env_logger = "0.3"
serde             = "1.0"
common-utils = { git = "ssh://[email protected]/common/common-utils.git", tag = "v0.0.1" }
common-log = { git = "ssh://[email protected]/common/common-log.git", branch = "master" }

这里的 common-utils common-log 就是私库的具体依赖。

common-utils = { git = "ssh://[email protected]/common/common-utils.git", tag = "v0.0.1" }
common-log = { git = "ssh://[email protected]/common/common-log.git", branch = "master" }

• 这里的git使用ssh方式访问

• tag :表示当前git上的tag号

• branch :表示当前git的 分支号
  通常，我们会采用tag对依赖的git代码管理；branch的缺点无法lock代码。

• 4. 执行cargo build
     正常情况下，cargo build可以正常下载crates.io和git私库代码
