`reader.hasNext()` is going to continue iterating through the document's tokens until it's completed, which lets us look through the entire document for the parts we need. The `selectName(JsonReader.Options)` method will return the index of a matched key, so `0` there means that the `heading` key was found. In response to that, we want to read it as a string and throw if it is null (since it's non-nullable in `TextParts`). The `Util.unexpectedNull` method is a little nicety that is part of Moshi's internals and is used by its kapt-generated adapters to provide better error messages and we're going to do the same. `reader.hasNext()` is going to continue iterating through the document's tokens until it's completed, which lets us look through the entire document for the parts we need.
