Definition of a lexer for the WebAssembly text format.
This module provides a Lexer
type which is an iterate over the raw
tokens of a WebAssembly text file. A Lexer
accounts for every single
byte in a WebAssembly text field, returning tokens even for comments and
whitespace. Typically you’ll ignore comments and whitespace, however.
If you’d like to iterate over the tokens in a file you can do so via:
use wast::lexer::Lexer;
let wat = "(module (func $foo))";
for token in Lexer::new(wat) {
println!("{:?}", token?);
}
Note that you’ll typically not use this module but will rather use
ParseBuffer
instead.
Structs

A parsed integer, signed or unsigned.
