apollo-compiler@0.4.0

Features

• add parser recursion limit API - SimonSapin, pull/353, issue/296

  Calling ApolloCompiler::with_recursion_limit instead of ApolloCompiler::new
  makes the compiler configure the corresponding parser limit.
  This limit protects against stack overflow and is enabled either way.
  Configuring it may be useful for example if you’re also configuring the stack size.

• expose the repeatable attribute on DirectiveDefinition - allancalix, pull/367

  There was previously no way to access the repeatable field on the DirectiveDefinition type.
  This field is required for validation rules.

• add type extensions - SimonSapin, pull/369

  apollo-compiler now partially supports GraphQL extend types. The is_subtype query takes
  extensions into account.

  Some other parts of the compiler, like validation, do not yet support extensions.

Fixes

• fix @include allowed directive locations - allancalix, pull/366

  The locations for the @include directive wrongly specified FragmentDefinition instead of FragmentSpread.
  It now matches the spec.

Maintenance

• avoid double lookup in SchemaDefinition::{query,mutation,subscription} - SimonSapin, pull/364
