Rust實際場景，不僅需要依賴https://crates.io/的公共mod，自己依賴的git私庫服務(wù)也是常見現(xiàn)象。
cargo正好也解決了私庫依賴的問題。詳細(xì)說明見鏈接：

cargo git私庫解決辦法

• 1. 添加.ssh/config配置

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

• 2. 指定私鑰文件

ssh-add -K ~/.ssh/id_rsa

• 3. cargo 的toml文件添加依賴，如下

[package]
name = "demo_rust"
version = "0.1.0"
authors = ["baoyachi <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://git@xxx.com/common/common-utils.git", tag = "v0.0.1" }
common-log = { git = "ssh://git@xxx.com/common/common-log.git", branch = "master" }

這里的 common-utils common-log 就是私庫的具體依賴。

common-utils = { git = "ssh://git@xxx.com/common/common-utils.git", tag = "v0.0.1" }
common-log = { git = "ssh://git@xxx.com/common/common-log.git", branch = "master" }

• 這里的git使用ssh方式訪問

• tag :表示當(dāng)前git上的tag號

• branch :表示當(dāng)前git的 分支號
  通常，我們會采用tag對依賴的git代碼管理；branch的缺點無法lock代碼。

• 4. 執(zhí)行cargo build
     正常情況下，cargo build可以正常下載crates.io和git私庫代碼
