Struct wagon_parser::parser::Parser

source ·
pub struct Parser<'source> { /* private fields */ }
Expand description

The main parser struct.

Uses a LexerBridge internally.

§Example

use wagon_parser::parser::Parser;
 
let s = "S -> A;";
let mut parser = Parser::new(s);
assert!(parser.parse().is_ok())
