A macro to define recursive parsers.

Parsers defined by this macro may be arbitrarily self-referential, unlike rule!.

Example

#![cfg(feature = "macros")]
#![feature(proc_macro_hygiene)]

use parze::prelude::*;

parsers! {
    foo = {
        '!' | bar
    }
    bar: Parser<_, _> = {
        '(' -& foo &- ')'
    }
}
