Bug Fixes

• The macro generated code now compiles under -D rust-2018-idioms

Bug Fixes

• Fix an issue where you'd get extremely weird compiler errors if your
  QueryFragment had fields named key or map.

Bug Fixes

• The generator and derive macros are now aware of the implicit __typename
  that every object & interface type gets.
• Fixed support for support fields with one or more leading underscores in the
  derives. This would have been possible before but only by using a rename
  attribute.

Bug Fixes

• Fixed a compilation error when targeting wasm with the http-reqwest feature
  enabled.

Bug Fixes

• Exposed the StreamingOperation type which was accidentally not exported in
  the move to v2.0.

Changes

• The use_schema output has been re-organised to reduce the chances of
  clashes. This is technically a breaking change, but only if you're writing
  queries by hand rather than using the derives.

New Features

• InlineFragments derives for union types now allow a fallback that receives
  the __typename

Bug Fixes

• schema_for_derives no longer ignores QueryVariables structs.
• A slight improvement on the error spans if you refer to a missing variable
  in some QueryFragment arguments.

Bug Fixes

• Some of the derives weren't recasing GraphQL types/fields correctly, leading
  to weird errors.
• Scalars defined using impl_scalar! couldn't be used as variables. Now they
  can.

This release contains a lot of breaking changes.

See the upgrade guide for help

Breaking Changes

• Cynic no longer supports providing variables via the arg.X syntax. Instead
  you should provide variables similar to how you would do in a GraphQL query:
  #[arguments(someArg: $my_variable)], where my_variable is a field on your
  QueryVariables struct.
• Arguments should be provided with the casing of the GraphQL schema rather
  than snake_casing them.
• Cynic now derives serde::Serialize and serde::Deserialize where
  appropriate so you can no longer do this yourself on structs you are using
  with cynic.
• Decoding GraphQLResponses should now be done directly with serde using a
  decode_response function on the operation (unless you're using an http
  extension trait, which will deal with this for you).
• Operation has changed:
  • It no longer has a lifetime.
  • It is now generic over the arguments type.
• The http extension traits have had their signatures changed to accomodate
  the new signature of Operation. Their use should still be the same.
• An Enum can no longer be shared between schemas. If you were doing this,
  you should define two Enums and provide conversion functions beteween the
  two of them.
• InlineFragments now always require a fallback and no longer perform
  exhaustiveness checking.
• QueryBuilder, MutationBuilder and SubscriptionBuilder no longer have a
  ResponseData associated type.
• QueryBuilder::build, MutationBuilder::build and
  SubscriptionBuilder::build now take their argument by value not by
  reference.
• The surf, reqwest & reqwest-blocking features have been renamed to
  http-surf, http-reqwest & http-reqwest-blocking respectively.
• The http-reqwest feature no longer uses the native-tls feature. Users
  should enable one of the tls features of reqwest themselves.
• The surf-h1-client, surf-curl-client, surf-wasm-client,
  surf-middleware-logger & surf-encoding features have been removed. If
  users want to enable these features in surf they should do it in their own
  Cargo.toml.
• cynic no longer re-exports serde_json
• The GraphQlError & GraphQlResponse structs no longer contain a
  serde_json::Value for extensions. They now have generic parameters that you
  should provide if you care about error extensions.
• The output of the use_schema macro is no longer re-cased.
• The deprecated query_module attribute for the various derive/attribute
  macros has been removed - if you're using it you should update to
  schema_module which behaves the same.

Deprecations

• The FragmentArguments trait & derive has been renamed to QueryVariables
• The argument_struct attribute for QueryFragment and InlineFragments has
  been deprecated in favour of variables

Bug Fixes

• Fixed a case where the generator would output the incorrect casing for some
  occurrences of a custom scalar in the output (#346)
• Cynic should now support schemas which have 2 similarly named but differently
  cased scalars.
• Cynic should no longer fail to compile in the face of various non-breaking
  schema changes.
• #[cynic(flatten)] no longer allows you to omit a list type on output fields.
  Previously this would compile but probably fail to deserialize.
• Non-nullable arguments & input object fields with defaults are no longer
  considered required

Changes

• Cynic now supports a new syntax for arguments:
  #[arguments(someArg: {"someField": 1})]
• cynic no longer uses inflector to re-case things. Hopefully this won't
  cause any regressions, but if it does please raise an issue.
• InlineFragments now take their expected typenames from the QueryFragment
  inside their variants, rather than from the name of the variants themselves.
• Queries output by cynic may have more literals in the GraphQL query string
  than they had in previous versions of cynic. Though the end result should
  be the same.
• use_schema output can now live in a separate crate from queries, which
  should help with large schema support. (The exception is impl_scalar
  invocations which must live in the same crate as the schema)
• Cynic now allows fields to be Arc or Rc
• The generator no longer outputs input types that are provided in argument
  literals, as these are no longer used in the generated code.

Breaking Changes

• The CynicReqwestError enum (behind the reqwest & reqwest-blocking
  feature flags) has a new variant to handle non 2XX responses from servers.
• Removed the GraphQlResult & PossiblyParsedData types (which weren't being
  used)
• Removed the following deprecated things: query_dsl!, the query_module
  module attribute, the GraphQLError, GraphQLResponse,
  GraphQLErrorLocation & GraphQlErrorPathSegment type aliases.

New Features

• The InlineFragments derive now supports a rename attribute on variants

Changes

• The QueryFragment derive now supports fields with types that take generic
  parameters directly, e.g. DateTime<Utc> from chrono. Previously this would
  have required a type alias to hide the generic parameters from cynic.

Bug Fixes

• The various HTTP client integrations will now return HTTP error details and
  the full body on non 2XX responses that don't contain a valid GraphQL
  response. Previously they would have tried to decode the response as GraphQL
  and returned the error from that operation.
