Struct Rule 

pub struct Rule {
    pub name: &'static str,
    pub root: u32,
    pub memoized: bool,
}

One rule.

Fields

name: &'static str

root: u32

The node its body compiled to. The matcher does not read this. A Rule node carries the same number in its b, so entering a rule is a field of a node already in a register rather than an index into a second table. This is here for the name lookup and for the tests.

memoized: bool

Whether upstream memoizes it. Twenty two rules do, and they are the ones deep in the expression grammar that a failing alternative re-enters at the same position over and over.
