Struct Node 

pub struct Node {
    pub op: Op,
    pub flags: u8,
    pub a: u32,
    pub b: u32,
}

One node. Twelve bytes.

Fields

op: Op

flags: u8

Per op. Only Identifier uses it today, for RESERVED.

a: u32

b: u32

Implementations

impl Node

pub const RESERVED: u8

On an Identifier node: the keyword check is dropped, so any word matches.

This is the whole of ReservedIdentifierMatcher. It is worth knowing that upstream applies it to the rule named ReservedKeyword, so a grammar rule that reads ColLabel <- ReservedKeyword / ... does not test for a reserved word, it accepts any word at all. Reading the grammar text alone would get that backwards.

pub fn children(self) -> &'static [u32]

The children of a sequence or a choice.
