根因分析

Go不允许在结构体中直接嵌入函数类型；只有接口类型可以被嵌入。

English

Go does not allow embedding function types directly in structs; only interface types can be embedded.

解决方案

  1. Define an interface type with the same method signature and embed that interface instead
  2. Use a named struct field with the function type

无效尝试

常见但无效的做法:

  1. 70% 失败

    Embedding requires a type name, not a value; a function field is a different semantic (has-a vs is-a).

  2. 90% 失败

    Aliases do not change the fundamental type category; embedding still fails.
