How to validate/receive MultiPartData in a type-safe way?
```validate&lt;MultiPartData&gt; { request -&gt;
    // perform validation
}```
If I do this, then all MultiPartData will be validated in the same way.

I’m looking for something like:
```call.receiveMultipart&lt;MyCustomMultiPartData&gt;()```
I tried implementing the MultiPartData interface, but not sure how to implement the readPart() method. Also `call.receive&lt;MyCustomMultiPartData&gt;()` will not receive as multipart

Unfortunately, that's impossible using the `RequestValidation` plugin. You can manually validate the parts while reading them up.
