Note that the variants of the enum are namespaced under its identifier, and we use a double colon to separate the two. The reason this is useful is that now both valuesIpAddrKind::V4andIpAddrKind::V6are of the same type:IpAddrKind. We can then, for instance, define a function that...

在Rust源代码中,rust/compiler/rustc_hir_analysis/src/check/compare_impl_item/refine.rs文件的作用是实现了一个用于比较和细化实现项的功能。 该文件中的主要结构是ImplTraitInTraitCollector<'tcx>,其作用是收集和处理带有impl Trait语法的trait实现项。
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。
We have seen how to use it with simple values, enums, Option, Result, and more complex patterns. The match expression is a powerful tool for control flow in Rust, allowing you to handle different cases in a clear and concise way. ...
