[−][src]Struct boa::syntax::lexer::Lexer
A lexical analyzer for JavaScript source code.
Fields
tokens: Vec<Token>
The list of tokens generated so far.
This field is public so you can use them once lexing has finished.
Implementations
impl<'a> Lexer<'a>
[src]
pub fn new(buffer: &'a str) -> Lexer<'a>
[src]
Returns a Lexer with a buffer inside
The buffer needs to have a lifetime as long as the Lexer instance itself
pub fn lex(&mut self) -> Result<(), LexerError>
[src]
Runs the lexer until completion, returning a LexerError if there's a syntax issue, or an empty unit result
Example
fn main() -> Result<(), LexerError> { let buffer = String::from("Hello World"); let mut lexer = Lexer::new(&buffer); lexer.lex() }
