rust: 引用第三方库（Cargo.toml、Cargo.lock文件）

接下来我要使用随机数生成函数，这个函数在 rand 库中。我们在 Cargo.toml 文件中的依赖项中，加入对 rand 的依赖说明。

[package]
name = "game"
version = "0.1.0"
authors = ["xuyeping"]
edition = "2018"# See more keys and their definitions at https://doc.rust-lang.org/cargo/reference/manifest.html[dependencies]
rand = "0.3.14"

“0.3.14” 说明我们要加入API与该版本号兼容的第三方库。运行 cargo build 命令，系统自动下载该库代码。

>>cargo runUpdating crates.io indexDownloaded libc v0.2.81Downloaded rand v0.3.23Downloaded rand v0.4.6Downloaded winapi v0.3.9Downloaded 4 crates (1.8 MB) in 3.41s (largest was `winapi` at 1.2 MB)Compiling winapi v0.3.9Compiling libc v0.2.81Compiling rand v0.4.6Compiling rand v0.3.23Compiling game v0.1.0 (E:\DiskZ\rust\0003-game)Finished dev [unoptimized + debuginfo] target(s) in 1m 57s

编译过程中自动生成的 Cargo.lock 文件，记录了相关资源信息，保证我们以后可以重新构建。

我看了一下，下载的代码包保存在 .cargo 文件夹下：
