Expand description

Token 类型枚举。

定义了 Onion 语言中所有可能的 Token 类型。每种类型对应不同的词法单元。

§Token 类型说明

  • NUMBER:数字字面量,包括整数、浮点数、十六进制、八进制、二进制
  • STRING:字符串字面量,支持多种引号格式和转义序列
  • IDENTIFIER:标识符,包括变量名、函数名、关键字等
  • SYMBOL:符号,包括运算符、分隔符、括号等
  • COMMENT:注释,包括单行注释和多行注释
  • BASE64:特殊的 Base64 编码字符串,格式为 $"..."

impl PartialEq<TokenType> for &Token

Source§

fn eq(&self, other: &TokenType) -> bool

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
