Trait Console 

pub trait Console: Sync {
    // Required method
    fn put_char(&self, c: u8);

    // Provided method
    fn put_str(&self, s: &str) { ... }
}

这个接口定义了向控制台“输出”这件事。

Required Methods

fn put_char(&self, c: u8)

向控制台放置一个字符。

Provided Methods

fn put_str(&self, s: &str)

向控制台放置一个字符串。

如果使用了锁，覆盖这个实现以免反复获取和释放锁。

In older versions of Rust, dyn compatibility was called "object safety".
