解析:这句话使用了 “not just…; it’s…” 的结构,用于强调 “error handling” 不仅仅是一个特性(feature),而是一个必需品(necessity)。 HowRustProvides Elegant Error Handling Through Its Type System Rust, a systems programming language, offers auniqueapproach to error handling, making it more type...
在之前的例子中,get和json函数返回了一个reqwest::Error错误。但是如果我们已经有了一个在调用其他的函数时返回的错误类型,那么我们应该怎么处理呢? 让我们通过返回格式化的日期而不是年份来扩展上一个示例: + use chrono::NaiveDate; use std::collections::HashMap; fn main() { match get_current_date...
