BC Breaks

  • #[graphql_object] and #[graphql_subscription] expansions now preserve defined impl blocks "as is" and reuse defined methods in opaque way. (#971, #1245)
  • Renamed rename = "<policy>" attribute argument to rename_all = "<policy>" (following serde style). (#971)
  • Redesigned #[graphql_interface] macro: (#1009)
    • Removed support for dyn attribute argument (interface values as trait objects).
    • Removed support for downcast attribute argument (custom resolution into implementer types).
    • Removed support for async trait methods (not required anymore).
    • Removed necessity of writing impl Trait for Type blocks (interfaces are implemented just by matching their fields now). (#113)
    • Forbade default implementations of non-ignored trait methods.
    • Supported coercion of additional nullable arguments and return sub-typing on implementer.
    • Supported rename_all = "<policy>" attribute argument influencing all its fields and their arguments. (#971)
    • Supported interfaces implementing other interfaces. (#1028)
  • Split #[derive(GraphQLScalarValue)] macro into:
    • #[derive(GraphQLScalar)] for implementing GraphQL scalar: (#1017)
      • Supported generic ScalarValue.
      • Supported structs with single named field.
      • Supported overriding resolvers with external functions, methods or modules.
      • Supported specified_by_url attribute argument. (#1003, #1000)
    • #[derive(ScalarValue)] for implementing ScalarValue trait: (#1025)
      • Removed Serialize implementation (now should be provided explicitly). (#985)
  • Redesigned #[graphql_scalar] macro: (#1014)
    • Changed from_input_value() return type from Option to Result. (#987)
    • Mirrored new #[derive(GraphQLScalar)] macro.
    • Supported usage on type aliases in case #[derive(GraphQLScalar)] isn't applicable because of orphan rules.

Added

  • #[derive(GraphQLInterface)] macro allowing using structs as GraphQL interfaces. (#1026)

Changed

  • Migrated to 2 version of syn crate. (#1157)

Fixed

  • All procedural macros expansion inside macro_rules!. (#1054, #1051)
