Codegen reimplementation for GraphQL unions (#666) - reimplement #[derive(GraphQLUnion)] macro to support: - both structs and enums - generics in type definition - multiple #[graphql] attributes - external resolver functions - remove From trait impls generation for enum variants - reimplement #[graphql_union] macro to support: - traits - generics in trait definition - multiple attributes - external resolver functions - GraphQLType implemetation for a raw trait object - GraphQLTypeAsync implemetation (#549) - add marker::GraphQLUnion trait - rewrite "2.5 Unions" section in Book (Juniper user documentation) - rewrite `codegen` and `codegen_fail` integration tests for GraphQL unions Additionally: - re-export `futures` crate in `juniper` for convenient reuse in the generated code without requiring library user to provide `futures` crate by himself (#663) - use unit type () as default context for EmptyMutation and EmptySubscriptions - relax Sized trait bound on some GraphQLType and GraphQLTypeAsync definitions, implementations and usages 2020-06-04 03:19:01 -05:00			`error: GraphQL union expects at least one union variant`
