因为我想在这一期中演示泛型的解码，所以类型信息需要包含泛型引用所使用的具体的参数类型。

Because I want to demonstrate decoding generic types for this column, the type information needs to include the specific parameter types used with a generic type reference.

在将某一约束应用于泛型类型参数时，必须存在从具体参数到该约束类型的隐式标识或引用转换。

When a constraint is applied to a generic type parameter, an implicit identity or reference conversion must exist from the concrete argument to the type of the constraint.

已知为引用类型的泛型类型参数。

Generic type parameters known to be reference types.
