Lone anonymous operation

A GraphQL document is only valid if when it contains an anonymous operation (the query short-hand) that it contains only that one operation definition.

See https://spec.graphql.org/draft/#sec-Lone-Anonymous-Operation

Implementation

Visitor loneAnonymousOperationRule(
  SDLValidationCtx ctx, // ASTValidationContext
) =>
    LoneAnonymousOperationRule();
