哪些是代客户采购，哪些是代理自营；哪些收入来自服务，哪些利润来自差价；客户有没有充分知情，能不能审计，能不能真正拒绝。这些问题如果说不清，效率越高，反而越危险。因为这意味着，交易摩擦被压低了，利益冲突却被包得更深了。。新收录的资料对此有专业解读
To understand why these rules are so important, we will walk through a concrete example known as the hash table problem. Let's say we want to make it super easy for any type to implement the Hash trait. A naive way would be to create a blanket implementation for Hash for any type that implements Display. This way, we could just format the value into a string using Display, and then compute the hash based on that string. But what happens if we then try to implement Hash for a type like u32 that already implements Display? We would get a compiler error that rejects these conflicting implementations.。业内人士推荐新收录的资料作为进阶阅读
