Example Code

• Snippet from Attr: https://github.com/skade/attr/blob/master/src/lib.rs (this classifies as strange code)

Language Lexic

Please see https://doc.rust-lang.org/grammar.html

• a list of reserved words (Did you know that “void” is a JavaScript keyword?)
  • https://doc.rust-lang.org/grammar.html#keywords
• rules for string and number literals (Can a double quoted string contain a newline?)
  • https://doc.rust-lang.org/grammar.html#literals
• rules for comments and other token types (Does Language have a special syntax for multiline comments?)
  • https://doc.rust-lang.org/grammar.html#comments
• a description of any unusual syntactic features (There’s this weird %w() thing in Ruby…)
  • Probably the ! which marks a macro. Such as println!().
• If there are different versions / implementations / dialects of this language: How do they differ?
  • There are none at this time.
