Enum SectionItemNode 

pub enum SectionItemNode {
    One {
        name: &'static str,
        child: u32,
    },
    Counted {
        name: &'static str,
        child: u32,
        count: u32,
    },
}

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

The count is a plain u32 and not the crate::ast::RepeatCount newtype: the invariant is discharged upstream, where the source span is still in hand to report the violation against, and the plan is a flat &'static repr the runtime reads without unwrapping anything.

Variants

One

name: P — one section.

Fields

name: &'static str

child: u32

Counted

name: repeated(P, N) — exactly count consecutive sections, collected into one Vec field. Never zero.

Fields

name: &'static str

child: u32

count: u32

Implementations

impl SectionItemNode

pub fn name(&self) -> &'static str

The record field this item contributes.

pub fn sections_wanted(&self) -> usize

How many sections this item consumes — the number the runtime’s section cursor advances by, and the number the shortfall check sums.

Trait Implementations

impl Debug for SectionItemNode

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
