Class Method Details
.deep_sync(val) ⇒ void
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.
This method returns an undefined value.
Traverse val
, triggering resolution for each GraphQL::Execution::Lazy.
These GraphQL::Execution::Lazys are expected to mutate their owner data structures
during resolution! (They’re created with the .then
calls in resolve_in_place
).

.each_lazy(acc, value) ⇒ void
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.
This method returns an undefined value.
If value
is a collection,
add any GraphQL::Execution::Lazy instances in the collection
to acc
