Struct Alt 

pub struct Alt {
    pub s: Vec<String>,
    pub b: usize,
    pub p: Option<String>,
    pub r: Option<String>,
    pub a: Vec<String>,
    pub g: String,
}

One alternative of a rule’s open or close list.

The fields are the jsonic alt fields this grammar uses: s (the token sequence to match), b (how many of those matched tokens to push back rather than consume), p (push a child rule), r (replace this rule), a (actions to run) and g (the alt’s tag groups).

Fields

s: Vec<String>

Token names this alt matches, in order. Empty matches unconditionally.

b: usize

Tokens to push back — matched, recorded, but left for the next rule.

p: Option<String>

The child rule to push after this alt’s actions run.

r: Option<String>

The rule to replace this one with after this alt’s actions run.

a: Vec<String>

Action references (@cssXxx), run in order.

g: String

Comma-separated tag groups, for diagnostics.
