库
让我们创建一个库,然后看看如何把它链接到另一个 crate。
pub fn public_function() { println!("called rary's `public_function()`"); } fn private_function() { println!("called rary's `private_function()`"); } pub fn indirect_access() { print!("called rary's `indirect_access()`, that\n> "); private_function(); }
$ rustc --crate-type=lib rary.rs
$ ls lib*
library.rlib
库的前缀为 “lib”,默认情况下它们跟随着 crate 文件命名(原文:by default they get named after their
crate file),但此默认名称可以使用 crate_name
属性 覆盖。
