If you were using Heroku Postgres, add a PostgreSQL container in the same application. Since containers in the same app share
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.，推荐阅读新收录的资料获取更多信息
