我可以通过在CompareTypeListtrait周围移动泛型而不是只在Compare关联类型上移动泛型来编译它。也许可以在不...

Or, phrased differently, when you heap-allocate memory, the result- ing pointer has an unconstrained lifetime—its lifetime is however long your program keeps it alive. The primary mechanism for interacting with the heap in Rust is the Box type. When you write Box::new(value), the value ...
编译器不会分析表达式（一般来说这也是不可能的）。它会进行逐字替换。如果你想编译这段代码，你需要用...
对于const 泛型,笔者也了解甚少。借写该文章的机会,学习一下Rust的const 泛型(Const Generics)。 const 泛型:也即是用常量值而不是类型作为泛型的参数。 const_unit_poc:利用const generics实现的物理单位库 const_unit_poc是几天前推出的,率先使用const 泛型的库。该库的使用方法如下: ...

It doesn't matter what the unconstrained lifetime is, but it doesn't have a default. But you can pretend it's 'static if you want I suppose. Functions Ignoring elision, function signatures with lifetimes have a few constraints: any reference must have an annotated lifetime. Elision covers ...
