Solution #2: Implement the Copy trait for the X structure. However, please keep in mind that the first solution should be preferred. #[derive(Clone, Copy)] struct X { x: (), } let x = Some((X { x: () }, X { x: () })); match x { Some((y, ref z)) => {}, None...
对于以JavaScript为主的Node.js开发者来说,你可能不太熟悉类似于“std::wx::y”或“&xyz”之类的表述,但是没关系,我会详细解释。 与JavaScript和Node.js相比,Rust是一门较为低级的语言。这意味着,你需要熟悉计算机的工作原理,才能真正理解Rust。而Node.js更为高级,通常接触不到这些表述。
