} T is an interface. The purpose of
is to make the method a little more flexible, but will there be performance problems if you use it too much?

Type conversion involves run-time security checks
in order to ensure type safety, type determination needs to perform a series of checking operations when Go is running.
also has a greater performance impact when converting interface A to interface B, because it needs to check and ensure that one interface implements another.
