Example

Lexing

```rust use webidl::*;

let lexer = Lexer::new("/* Example taken from emscripten site */\n\ enum EnumClassEnumWithinClass {\n\ \"EnumClass::eval\"\n\ };"); asserteq!(lexer.collect::>(), vec![Ok((41, Token::Enum, 45)), Ok((46, Token::Identifier("EnumClassEnumWithinClass".tostring()), 71)), Ok((72, Token::LeftBrace, 73)), Ok((74, Token::StringLiteral("EnumClass::eval".to_string()), 92)), Ok((93, Token::RightBrace, 94)), Ok((94, Token::Semicolon, 95))]); ```

Parsing

```rust use webidl::; use webidl::ast::;

let result = Parser::parse_string("[Attribute] interface Node { };");

asserteq!(result, Ok(vec![Definition::Interface(Interface::NonPartial(NonPartialInterface { extendedattributes: vec![ Box::new(ExtendedAttribute::NoArguments( Other::Identifier("Attribute".tostring())))], inherits: None, members: vec![], name: "Node".tostring() }))])); ```
