v0.4.0

Breaking Changes

• schema_path parameters are now relative to CARGO_MANFIEST_DIR rather than
  the current working directory. This fixes an issue with cargo workspace
  projects where doc-tests would be relative to the sub-crate but cargo builds
  were relative to the workspace root. For projects not using workspaces this
  will probably make no difference
• The query_dsl has been reworked. Before each field with arguments had one
  or two structs: one for optional arguments & one for required arguments, and
  these were passed to the selector function before the selection set argument.
  Now each selector function takes the required arguments, and then returns a
  struct that follows the builder pattern to allow for optional arguments to be
  added. This fixes a few issues and is a bit more ergonomic.

Bug Fixes

• Fixed a bug where any type used as an optional argument needed to implement
  Default. This was fixed by the query_dsl rework.
• Fixed a bug where optional arguments that were enums or interfaces had to be
  provided or type inference problems occurred. This was also fixed by the
  query_dsl rework.

v0.3.0

New Features

• Added chrono::DateTime scalar support behind a chrono feature flag.
• The cynic::selection_set module and all it's contents are now documented.
• QueryBody now exposes it's arguments & query fields for greater flexibility
  (and use in snapshot testing etc.)

Bug Fixes

• Generated query_dsl now disables unused import warnings where appropriate.
• Exposed Id::inner & Id::into_inner functions - these were meant to be
  public but were not
• Cleaned up a ton of compiler warnings - mostly unused imports and a few unused
  variables
• query_dsl adds allow(dead_code) annotations so we don't get tons of dead
  code warnings when we're not exercising an entire schema.
• query_dsl no longer creates mutable Vec for fields without arguments -
  this was leading to tons of "doesn't need to be mutable" warnings.
• ID fields are now correctly given the cynic::Id type in query_dsl - previously
  they were being forced to String.
• cynic::Id is now a cynic::Scalar
• Fixed an issue in derive(QueryFragment) where Enums inside lists would not be
  treated as Enums.
• DecodeError now implements std::error::Error

v0.2.0

Breaking Changes

• The generated query_dsl no longer contains generated enums - users should
  provide their own enums and derive(cynic::Enum) on them. Cynic querygen
  can be used to help with this.
• The generated query_dsl no longer contains generated input objects - users
  should provide their own structs and impl cynic::InputObject on them. A
  derive for this should be coming in the future.

New Features

• Union types can be queried via #[derive(InlineFragments)] on an enum.
• Schemas that use interfaces are now supported, though interfaces are not
  yet queryable.
• #[derive(QueryFragment)] now explicitly checks for required/list type
  mismatches & other easy mistakes, and warns the user appropriately.
• Added an output_query_dsl function suitable for running inside build.rs
• Added a flatten option at the field level. When present this will flatten
  nested options & vectors into the provided type. Used to handle the common
  case in GQL where someone has defined an optional list of optionals. This is
  a pain in Rust, since the same thing can usually be represented by a
  non-optional list of non-optionals.
• Added a cynic-querygen for generating QueryFragment structs from a graphql
  schema & query. This currently has a WIP web interface and a WIP CLI, though
  neither of them are particularly user friendly at this point.
• Added a cynic::query_module attribute macro that can be applied to modules
  containing QueryFragments & InlineFragments. When this attribute is present
  the derive will be done for all QueryFragments & InlineFragments contained
  within. This allows users to omit some of the parameters these derives
  usually require, as the query_module attribute provides them and fills them
  in. These modules may be expanded in the future to provide more
  "intelligent" features.
• Added support for mapN up to N = 50, therefore adding support for GraphQL
  objects with up to 50 fields.
• Added new cynic::Enum derive that matches up a Rust enum with a GraphQL enum.
  cynic-querygen will automatically provide enums using this derive when a
  query includes an enum.
• Added SelectionSet::and_then for chaining decode operations on selection sets.
• Added cynic::Scalar derive for newtype structs so that users can easily
  define their own scalars. Also added support for this to cynic-querygen
• Added cynic::Id type to handle Ids in queries.
• Added cynic::InputObject trait to allow the query_dsl to handle
  InputObjects generically.

Changed

• Split the procedural macros out into their own cynic-proc-macros crate.
  cynic-codegen now exists as a re-usable library for programatically
  doing the codegen.
• The IntoArguments trait is now named FromArguments and has had it's
  parameters switched up.
• Added a StarWars API example

Bug Fixes

• Now supports schemas that define their root query types. Before we just
  assumed there was a type called query.
• Fixed a few things that stop the examples in the documentation from
  compiling.
• Fixed all the tests
• We now use the correct case for non built-in scalar types
• Fixed an issue that prevented propagation of argument structs into inner
  QueryFragments
