v0.11.0

Breaking Changes

• QueryFragment::fragment now accepts a FragmentContext rather than
  arguments. This change was neccesary to support recursive queries.
• It is no longer recommended to use QueryFragment::fragment directly -
  instead an Operation should be constructed with QueryBuilder::build or
  MutationBuilder::build. Note that these return an Operation so you no
  longer need to construct one manually.
• GraphQL fields with names that match rust keywords will no longer be
  postfixed with a _ - you should now use a raw identifier (or rename) for
  these fields.
• Derived Enums now default to rename_all = "SCREAMING_SNAKE_CASE" if not
  provided. To revert to the old behaviour you should explicitly provide "None"
• Derived InputObjects now default to rename_all = "camelCase" if not
  provided. To revert to the old behaviour you should explicitly provide
  rename_all = "None"
• Removed the kebab-case & SCREAMING-KEBAB-CASE rename_all rules - fairly
  sure kebab case is not valid in GraphQL so this shouldn't affect much.

New Features

• Cynic now supports recursive queries via the #[cynic(recurse="N")]
  attribute on fields that recurse.
• The generator now understands query fragments, spreads and inline fragment
  spreads. Inline fragments for interface/union types are not yet supported.
• Interfaces can be queried via #[derive(InlineFragments)] on an enum.
• Added support for using chrono::NaiveDate as scalars. The decode/encode
  functions will convert to/from dates in the ISO 8601 format, that is
  YYYY-MM-DD
• Added QueryBuilder & MutationBuilder traits for constructing Operations
  from QueryFragments.

Bug Fixes

• The generator (and therefore the generator tests) should now work when run on
  windows.
• Paths output as part of generator are now all raw strings, so should support
  windows path separators.
• The generator now correctly wraps literal ID parameters with cynic::Id::New
• Cynic derives (and cynic itself) no longer emit clippy warnings (on 1.48 at least)
• We now support raw identifiers in QueryFragment derives, useful for fields
  named type or similar.
• The generator now correctly renames InputObject fields & Enum variants if the
  default rename_all doesn't work for them.
• The InputObject derive no longer looks up scalars inside query_dsl (which
  required them to be pub used in query_dsl).
• The generator is now context aware with argument values, and does a better job
  of figuring out whether to clone or take by reference.

Changes

• The generator is now a lot more thorough, it:
  • Deduplicates generated types
  • Supports multiple queries, sharing structs between all the generated queries
    as appropriate.
  • Generates unique names for each struct it creates, even when faced with
    different structs targetting the same type.
  • Generates partial InputObjects when faced with literals with missing fields
    (previously it would generate all fields even when unused)
  • Correctly generates different argument structs if a single type with
    arguments is used in multiple queries. Though the correct IntoArgument impl
    is not yet generated.
• The generator now generates scalars with public fields
• The generator now derives Clone on scalars as certain positions they can
  appear in require cloning
• The generator now outputs correct Rust code when faced with queries that rely
  on list coercion.
• rename_all attribute is no longer case sensitive.
• Improved the docs for attributes in the book
