值得注意的是,在Rust 中, 从String 类型转变为 &str 是非常便捷的,而且无损的(性能无损,不会造成重写malloc或者数据移动)。 或者,直接通过String 调as_str 获得所有元素的切片引用: fn learn_str() { let hs = String::from("Rustlang -杜鲁门"); let xp = hs.as_str();} 但反过来,从一个&str 获得...
一个简陋的 args 解析器 您可能想要使用切片模式的另一种方法是“剥离出”所需的前缀或后缀。 虽然已有 clap 和 structopt 这样复杂命令行解析工具,但我们可以使用切片模式来实现自己的基本参数解析器。 fn parse_args(mutargs: &[&str]) -> Args { ...
