which does not implement the `Copy` trait error: aborting due to 2 previous errors 啊哈!第一个错误信息中说,counter 所有权被移动进了 handle 所代表线程的闭包中。因此我们无法在第二个线程中再次捕获 counter , Rust 告诉我们不能将 counter 的所有权移动到多个线程中。所以错误原因明朗了,因为我们在循环...

move occurs because `string_obj` has type `String`, which does not implement the `Copy` trait 1. 在值对象的示例中,并没有这样的错误,也由此可推断值对象是实现了Copy Trait的,并且在作用域切换的场景中,直接使用Copy,在官方文档中,关于Copy特别说明了是简单的二进制拷贝。
