Class Method Details
.continue_or_wait(raw_value, field_type, field_ctx) ⇒ Object
This method is part of a private API. You should avoid using this method if possible, as it may be removed or be changed in the future.
If the returned object is lazy (unfinished),
assign the lazy object to .value=
so we can resolve it later.
When we resolve it later, reassign it to .value=
so that
the finished value replaces the unfinished one.
If the returned object is finished, continue to coerce and resolve child fields
