Enum SectionItem 

pub enum SectionItem {
    One {
        name: String,
        parser: ParserAst,
    },
    Counted {
        name: String,
        count: RepeatCount,
        parser: ParserAst,
    },
}

One named argument of a heterogeneous sections(...) other than its unbounded tail (§7.5).

Each variant contributes exactly one field to the generated record; they differ in how many sections they consume, which is what sections_wanted answers. The count lives in the item rather than in a parallel position map beside the field list, because a position recorded twice is a position that can disagree with itself — which is the drift ADR-073 was written about.

Variants

One

name: P — one section, one field of result(P).

Fields

name: String

parser: ParserAst

Counted

name: repeated(P, N) — exactly N consecutive sections, one field of Vec[result(P)].

Fields

name: String

count: RepeatCount

parser: ParserAst

Implementations

impl SectionItem

pub fn name(&self) -> &str

The record field this item contributes.

pub fn parser(&self) -> &ParserAst

The parser applied to each of this item’s sections.

pub fn parser_mut(&mut self) -> &mut ParserAst

The parser, mutably — for ParserAst::shift_spans.

pub fn sections_wanted(&self) -> usize

How many sections this item consumes.
