A Java token

This enum differs a bit from the original definition in the Java spec, in which this Token is called InputElement and is defined as: WhiteSpace | Comment | Token The Java-*Token* is defined as: Identifier | Keyword | Literal | Seperator | Operator

This Token type differs from the formal and correct definition to make the parser and lexer module less verbose. The differences are: - all 5 variants of the Java-*Token* are direct variants of this Token - therefore the name Java-*Token* is not necessary and Java's InputElement is called Token instead - *Seperator*s and *Operator*s are also direct variants of this Token

Methods

impl Token

fn is_real(&self) -> bool

Returns true if the token is a "real" token (aka. a Java-*Token*)

fn as_java_string(&self) -> &str

String for error reporting. Example: Excpected one of `,` `;` `)`

Trait Implementations
