Features

• parse_type parses a selection set with optional outer brackets - lrlna, pull/718 fixing issue/715
  This returns a SyntaxTree<Type> which instead of .document() -> cst::Document
  has .type() -> cst::Type.
  This is intended to parse the string value of a @field(type:) argument
  used in some Apollo Federation directives.

  let source = r#"[[NestedList!]]!"#;
  
  let parser = Parser::new(source);
  let cst: SyntaxTree<cst::Type> = parser.parse_type();
  let errors = cst.errors().collect::<Vec<_>>();
  assert_eq!(errors.len(), 0);

Fixes

• Input object values can be empty - goto-bus-stop, pull/745 fixing issue/744
  apollo-parser version 0.7.3 introduced a regression where empty input objects failed to parse.
  This is now fixed.

  { field(argument: {}) }
