Struct LayoutResult 

pub struct LayoutResult {
    pub graph: PageGraph,
    pub diagnostics: Vec<Diagnostic>,
    pub label_pages: BTreeMap<String, u32>,
}

Result of laying out a [mos_core::Document]: a PageGraph plus any warnings the engine emitted. Mirrors mos_eval::LowerResult so the CLI can render diagnostics uniformly.

Fields

graph: PageGraph

diagnostics: Vec<Diagnostic>

label_pages: BTreeMap<String, u32>

Map from a declared label to the 1-based number of the page its target first lands on (issue #72). Built during layout as each labelled block commits its first content; first placement wins, so a label on a block that spans pages maps to its start page, and a labelled block that produced no content is absent.

This is the layout-side half of page-reference resolution: the resolve↔layout fixpoint feeds this map back into the resolver so @page(label) can render the target’s printed page number. It lives on the result rather than the PageGraph because it feeds the resolver, not the PDF backend, which consumes only graph.

Implementations

impl LayoutResult

pub fn page_boundary_signatures(&self) -> PageGraphSignature

The page boundary signatures of this layout’s PageGraph (design note §4.5). Convenience for cache/reflow consumers.

Trait Implementations

impl Debug for LayoutResult

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

Formats the value using the given formatter.
