Backend/orchestrator capable of lowering any advertised graph node to mesh.

Implementations must return axiolid_contracts::GeomError::Unsupported for a node they do not support. They must not silently omit it or approximate exact geometry unless the execution policy explicitly permits that precision.

Required Methods

fn compile_mesh( &self, graph: &GeometryGraph, root: NodeId, options: &ExecutionOptions, ) -> GeomResult<TriMesh>

Compile one root.

Provided Methods

fn scratch_requirement(&self) -> ScratchRequirement

Scratch this compiler needs beyond the graph and the produced meshes.

Defaults to ScratchRequirement::Unbounded: an unaudited compiler is treated as unbudgetable rather than silently assumed cheap.

fn output_bound(&self) -> OutputBound

Outputs produced per requested root.

Compilation is one mesh per root, so the destination size is known before the batch runs and workers can write disjoint slots.

fn compile_mesh_reported( &self, graph: &GeometryGraph, root: NodeId, options: &ExecutionOptions, ) -> GeomResult<CompileOutcome>

Compile one root and report what happened to each attribute channel.

The default wraps Self::compile_mesh and reports CompileOutcome::attribute_fates as None (not tracked). A compiler that carries channels overrides this so a caller can tell a dropped channel from one that was never there.

fn compile_mesh_batch_into( &self, graph: &GeometryGraph, roots: &[NodeId], options: &ExecutionOptions, destination: &mut Vec<TriMesh>, ) -> GeomResult<()>

Compile roots into a caller-provided buffer.

This is the seam a batching implementation should override: the caller owns the destination, so a provider can reserve once from Self::output_bound and have workers write disjoint slots instead of growing a vector under a lock. destination is appended to, never cleared, so results can be accumulated across calls.

The default is a serial loop over Self::compile_mesh, which stays the only required primitive.

fn compile_mesh_batch( &self, graph: &GeometryGraph, roots: &[NodeId], options: &ExecutionOptions, ) -> GeomResult<Vec<TriMesh>>

Compile roots as a batch.

Convenience over Self::compile_mesh_batch_into; overriding that instead gives both call shapes the batched behaviour.
