Get requested fields in resolver

[bartenra]

Hello!

I am wondering if there is a library that allows me to get the requested fields on the object of a current resolver. You'd need to parse info (GraphQLResolveInfo) for this. In the JS world there's this:

https://www.npmjs.com/package/graphql-parse-resolve-info (see Stack Overflow question here).

My use case is that I want to add directives to a certain object like so:

type MyObject {
  id: ID! @public
  field: String! @public
  otherField: [SomeOtherObject!]!
}

And then check in a resolver if only public fields are being requested (those with @public directive), in which case the permissions check should be skipped.

I'm not aware of such library existing for graphql-core (library Ariadne uses for GraphQL implementation).
