A multiline string refers to a string literal that can span multiple lines. Multiline strings are a common occurrence in programming. For example, you can use the multiline strings to store a large text such as an extensive SQL query. In this tutorial, we will learn the various methods th...

这个lines返回一个迭代器,迭代器的元素是Result<String, std::io::Error>类型的,它们来自request的stream,然后被切割成一项一项的。切割的过程自然是有可能出错的,比如需要转换成字符串,如果这个数据不符合utf-8的编码,那就会出问题了。 然后我们用map迭代这个迭代器,用unwrap将Result<T, E>里的string拿出来。 ...
字符串类型(String) Rust 中的字符是 Unicode 类型,因此每个字符占据 4 个字节内存空间,但是在字符串中不一样,字符串是 UTF-8 编码,也就是字符串中的字符所占的字节数是变化的(1 - 4)。 Rust 在语言级别,只有一种字符串类型: str,它通常是以引用类型出现 &str,也就是上文提到的字符串切片引用。虽然语言...

StyledString用于构建带有样式的字符串,以便于在终端中正确展示错误信息。 AnnotationType和Style用于指定注解和样式的类型。 通过使用这些struct和enum,rust/compiler/rustc_errors/src/snippet.rs文件能够生成良好格式化的代码片段,并且可以根据注解类型和样式选项进行适当的样式设置。这样做的目的是为了更好地呈现错误信息,...
