SectionItemNode

Enum SectionItemNode 

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

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§

Source§

impl SectionItemNode

Source

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

The record field this item contributes.

Source

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.
