I don't understand the with_configured_adapter. Could you show me a situation where it makes sense?

[bf4]

Does the comment at the top of the method answer that question?

[bf4]

Before SerializableResource, the only way to specify an adapter was global, as an option to render, or by building the serializer and adapter yourself.. now we don't need global quite as much

[beauby]

Oh, I got it. I was reading that as "do stuff with the adapter I'm providing, that I have given a specific configuration", instead of "do stuff with this adapter by setting it as the configured adapter".
