A raw string literal necessarily starts and ends withat least3x double quote characters""".At leastis in bold because more than three double quote characters can be used for delimiters. With the"""delimiter the literal can contain"and""sub-strings. With the"""delimiter the literal can contai...
原始字符串字面量(raw string literal)是可以横跨多行代码的字符串字面量,不需要转义嵌入的双引号,像\t和\1!这种转义序列不按照转义序列的方式处理,而是按照普通文本的方式处理。如果像下面这样编写普通的字符串字面量,那么会收到一个编译器错误,因为 字符串包含了未转义的引号: string str = "Hello "World"!

"Raw string literal" support has been added to C# 11, which you can now use in Visual Studio 2022. To use the raw string literals, you need to set the C# language version in your project file to preview (usingpreview). Visual Studio 2022 version 17.2 will also allow you to quickly re...
在Redis里面,C字符串只会作为字符串字面量(string literal)用在一些无须对字符串值 进行修改的地方,比如打印日志: redisLog(REDIS_WARNING,"Redis is now ready to exit, bye bye..."); 1. 当Redis需要的不仅仅是一个字符串字面量,而是一个可以被修改的字符串值时,Redis 就会使用SDS来表示字符串值,比如...

Alternatively, we could unravel CStr and CStrRaw literals into two tokens (Ident and Str / StrRaw) after the fact in rustc_parse::lexer where we have access to the edition, although that's a bit messier I guess (and other parsers like rust-analyzer's would need to remember this step ...
