How can I prevent JSON from being unmarshaled into a field of a struct in Go?

Marshaling the field is fine, so using the tag json:"-" won't work. I could use the UnmarshalJSON method on the struct, but I have no idea how to implement it.

I'd rather not make a duplicate of the struct with that field removed, as it causes quite a bit of code duplication, and it's pretty chaotic.

  1. Ask the main part of your question in the title. This should be concise but informative.

  2. Provide everything up front. Don't make people fish for more details in the comments. Provide background information and examples.

  3. Be present for follow up questions. Don't ask for help and run away. Stick around to answer questions and provide more details.

  4. Ask about the problem you're trying to solve. Don't focus too much on debugging your exact solution, as you may be going down the wrong path. Include as much information as you can about what you ultimately are trying to achieve. See more on this here: https://xyproblem.info/
