Custom Keys

It may be that you want to name your properties in your object something different to what is in the data. This can be for readability reasons, or because you have to (such as if your data item is named __class__). This can be handled too. Simply use the key annotation as follows:

@deserialize.key("identifier", "id")
class MyClass:
    value: int
    identifier: str

This will now assign the data with the key id to the field identifier. You can have multiple annotations to override multiple keys.
