所以需要在 T 的 trait bound 中指定PartialOrd,这样largest函数可以用于任何可以比较大小的类型的 slice,当然代码还是会报错: 又回到了之前说的所有权系统,list item 的所有权不能被转移(move),只有 Copy 行为才可以这样操作,所以必须要加上T: ``PartialOrd + Copy这样的 bound 才可以通过编译; 动态大小类型 绝...
// This prints "in", then "out" fn main() { let x = "out"; { // this is a different `x` let x = "in"; println!(x); } println!(x); } 代码块也是表示式,表示其计算为一个值。 代码语言:javascript 复制 // this: let x = 42; // is equivalent to this: let x = { 42...
类似于TypeId,ThreadId也是实现了Copy和Eq特性的结构体。ThreadId的作用是在多线程环境中唯一标识一个线程。 TypeInfo结构体代表一个类型的详细信息。它包含了类型的名称、大小以及对齐方式等。TypeInfo结构体通常通过type_of函数获取,该函数接受一个静态类型作为参数并返回对应类型的TypeInfo。 除了上述结构体,该文件还...

They both appear to work identically. Well, they have different types, so I'm not sure how you can say that (other than because arrays such as B coerce to slices such as A)? They also have different ... eggyal 125k answeredSep 26 at 4:47 ...
