Enum wast::lexer::Source

pub enum Source<'a> {
    Comment(Comment<'a>),
    Whitespace(&'a str),
    Token(Token<'a>),
}

A fragment of source lex'd from an input string.

This enumeration contains all kinds of fragments, including comments and whitespace. For most cases you'll probably ignore these and simply look at tokens.

Variants

Comment(Comment<'a>)

A fragment of source that is a comment, either a line or a block comment.

Whitespace(&'a str)

A fragment of source that represents whitespace.

Token(Token<'a>)

A fragment of source that represents an actual s-expression token.

Methods

impl<'a> Source<'a>

pub fn src(&self) -> &'a str
