Support for OneOf Input Objects

[RobVermeer]

Hey there!

I can't seem to find any information on support for the @oneOf directive in Apollo client (React). Is this on the roadmap? I see that it's being implemented in other places as well. 🙏

Some relevant links:

• RFC: OneOf Input Objects graphql/graphql-spec#825
• feature: @oneOf input object support apollo-ios-dev#537
• Support @oneOf for Input Objects apollo-kotlin#5431
• feat: Add Support for @oneOf Input Object Directive webonyx/graphql-php#1715

I believe there is nothing we would need to do here on the Apollo Client side, as Apollo Client just takes the variables you give it and sends them to the server, and we don't have any runtime checks on variables.

This feels like it should be more something tackled on the side of TypeScript codegen, which could generate types that are mutually exclusive?

Ahh that makes sense! Thanks!
