pub struct LayoutEngine<'a> { /* private fields */ }

Deterministic measure → propose → query → resolve → commit engine.

Implementations

impl<'a> LayoutEngine<'a>

pub fn new( limits: &'a ResourceLimits, fonts: &'a FontManager, options: LayoutOptions, ) -> Result<Self>

Creates an engine over explicit limits and fonts.

pub fn new_controlled( limits: &'a ResourceLimits, fonts: &'a FontManager, options: LayoutOptions, control: OperationControl, ) -> Result<Self>

Creates an engine with cooperative cancellation and progress controls.

pub fn with_assets(self, assets: &'a dyn AssetResolver) -> Self

Supplies the explicit resolver needed to resolve image paint geometry.

pub fn resolve(&self, document: &DocumentIr) -> Result<ResolvedScene>

Resolves all geometry before any exporter is selected.

pub fn resolve_cached( &self, document: &DocumentIr, fingerprint: DocumentFingerprint, cache: &mut SceneCache, ) -> Result<Arc<ResolvedScene>>

Resolves only on a fingerprint miss and returns an immutable shared scene.

The fingerprint must be computed from the same template, data, patches, assets, and fonts used to produce document and this engine.
