Unions and enums

Corvis does not include GraphQL support: there is no module, no resolvers, no schema generation and no GraphQL server. Corvis APIs are currently exposed over HTTP with controllers, WebSockets and Server-Sent Events.

There are no GraphQL unions or enums.

Alternative

• For read and write APIs, use REST controllers and document the contract with OpenAPI.
• To validate and shape inputs, use corvis::z schemas.
• z::union, z::discriminated_union and z::enum_ validate those shapes in JSON (see Validation).
