/**
* No deprecated
*
* A GraphQL document is only valid if all selected fields and all used enum values have not been
* deprecated.
*
* Note: This rule is optional and is not part of the Validation section of the GraphQL
* Specification. The main purpose of this rule is detection of deprecated usages and not
* necessarily to forbid their use when querying a service.
* @param context - The validation context used while checking the document.
* @returns A visitor that reports validation errors for this rule.
* @example
* ```ts
* import {
* GraphQLObjectType,
* GraphQLSchema,
* GraphQLString,
* parse,
* validate,
* } from 'graphql';
* import { NoDeprecatedCustomRule } from 'graphql/validation';
*
* const schema = new GraphQLSchema({
* query: new GraphQLObjectType({
* name: 'Query',
* fields: {
* name: { type: GraphQLString },
* oldName: {
* type: GraphQLString,
* deprecationReason: 'Use name instead.',
* },
* },
* }),
* });
*
* const invalidDocument = parse(`
* { oldName }
* `);
* const invalidErrors = validate(schema, invalidDocument, [NoDeprecatedCustomRule]);
*
* invalidErrors.length; // => 1
*
* const validDocument = parse(`
* { name }
* `);
* const validErrors = validate(schema, validDocument, [NoDeprecatedCustomRule]);
*
* validErrors; // => []
* ```
