- generate always `::juniper::` crate path in proc macros and use `extern crate self` to make it work inside `juniper`
- add optional non-documented `internal` proc macro argument to proc macros, which allows double-underscored names and is used inside `juniper` only
- add object safe GraphQLValue, GraphQLValueAsync and GraphQLSubscriptionValue traits containing methods for value resolution
- refactor GraphQLType, GraphQLTypeAsync and GraphQLSubscriptionType traits to register and provide GraphQL type information only
- 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
* Implemented most test cases from the specification
* Unified error handling for all generators
- Removed proc-macro-error -> not required -> use syn::Error
- Everything below lib.rs uses proc_macro2::TokenStream
instead of proc_macro::TokenStream
- Replaced error handling in attribute parsers
* WIP better error messages for *all* macros
* Refactored GraphQLInputObject and minor tweaks
- removed support for Scalar within a string ("DefaultScalarValue")
- removed unraw function and replaced it with the built-in one
- added error messages and return types for all functions within utils
- added more constraints to fulfill the GraphQL spec
* Fixed test-cases which are not compliant with the specification
* Removed unused function
* Added constrains, updated error messages, added marker
* Added argument rename within impl_graphql and fixed `__` tests
* Formatted and cleanup
* Added GraphQLTypeAsync for input object
* Moved codegen tests to separate module
Nightly and stable produce different outputs, thus only test nightly.
* Added IsInputType/IsOutputType traits for type checking

* Updated implementation of derive enum
- allows context specification
- allows scalar specification
- shares code with derive object
* Added this feature to CHANGELOG
* Added matrix with supported macro attributes for enums
* Added case which checks for custom context
* GraphQLUnion now can use a different context per variant
* Moved context switch test for union into right folder
* Sync resolve expression has the same form as the other impls
* Disabled custom scalar on GraphQLEnum
* Fixed CHANGELOG
* Fixed support matrix of GraphQLEnum in the book
- scalar not supported!
- skip not supported!
* Added test case for "noasync" derive attribute
* Disallowed generics and lifetimes on GraphQLEnum
* Added error message for duplicate naming
* Added error message for empty variant
* Implemented device macro for GraphQLUnion's
* Updated PR link in CHNAGELOG
* Disabled documentation on enumeration fields
* Disabled skip on fields
* Changed implementation for std::convert::Into since skip is not possible
* Added documentation for GraphQLUnion
* Added tests for GraphQLUnion
* Fixed typos in error messages (as suggested by review)
* Fixed failing documentation example
* Utilized `resolver_code` in `util::GraphQLTypeDefinitionField`.
Simplifies code and provides the idea of using
`util::GraphQLTypeDefinitionField` for different types than objects.
* Removed wrong statement about skip annotation in docs.
