When the required fields are not properly provided, the compiler cannot deduce the build function. In that time, the compile error message would be like this:
no method named `build` found for struct `TestBuilder<...>` in the current scope
It will be helpful that the compiler suggests missing required fields like this:
Cannot build `Test` because following fields are required:
- name: String
- age: u8
It may be easily implemented if the Specialization feature is implemented, but the feature is not stable.
