Struct DirectiveMark 

pub struct DirectiveMark {
    pub name: String,
    pub attrs: Vec<(String, Option<String>)>,
    pub label: String,
    pub rows: usize,
}

The name and attributes a leaf directive’s placeholder row carries, so a frontend that knows the host app’s vocabulary can paint the real thing — an embedded page for diaryx’s ::embed{src=…}, a generated table of contents for a ::toc, and the plain ⧉ name label for one it doesn’t know. The peer of MediaMark, and plain strings for the same reason: they survive the row shuffling of BlockCache reuse and build_spliced.

Fields

name: String

The directive’s type — embed, toc, vis — with no leading colons. Core is agnostic of what it means: the vocabulary is the host app’s.

attrs: Vec<(String, Option<String>)>

Its {…} attributes as (key, value) pairs in source order. A bare attribute ({public}) has a None value, the way twig reports it.

label: String

The directive’s [label] text, flattened from its inline children, or empty when it has none. Also what the placeholder label shows.

rows: usize

How many visual rows this directive reserves — the label row plus blank filler rows below it, so a frontend painting something real has the vertical room. 1 is the bare placeholder, and what every directive gets until a frontend that reserves rows — a terminal, which draws the host’s lines over them — reports a height back through crate::Doc::set_directive_rows, keyed by key. A pixel-laid-out GUI sets its own height regardless.
