Struct ThreadRunner 

pub struct ThreadRunner { /* private fields */ }

The persistent-thread runner. submit_*/reset push Commands down the channel; poll_* first DRAIN every ready Reply into the two demux buffers, then pop the matching one. The SceneRunner (and thus the kernel’s resident registry it warms) lives ENTIRELY on the thread — it is never shared — so the only cross-thread traffic is the Send command/reply payloads.

Implementations

pub fn new() -> Self

Trait Implementations

impl Default for ThreadRunner

Available on non-WebAssembly only.

fn default() -> Self

Returns the “default value” for a type.

impl Drop for ThreadRunner

Available on non-WebAssembly only.

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.

impl HistoryRunner for ThreadRunner

Available on non-WebAssembly only.

fn cancel(&mut self) -> bool

Abandon the thread: raise its stop flag, close its channels, and spawn a fresh thread with a fresh registry. The old thread cannot be interrupted inside a feature — it finishes the one it is on (burning CPU until then), sees the flag, and exits. Always true: there is always a thread to replace.

fn submit_run(&mut self, request: HistoryRequest, generation: u64)

Submit a history run tagged with a monotonic generation. The runner executes it (immediately for Inline; on a background thread later) and makes the reply available via poll_run.

fn sync_parts_library( &mut self, revision: u64, fetch: &mut dyn FnMut() -> PartsLibraryMap, )

Bring the runner’s resident PARTS LIBRARY up to revision, calling fetch ONLY when it is not already there. Called immediately before every submit_run.

fn poll_library_request(&mut self) -> bool

True when the runner REFUSED a run because its resident parts library could not serve it (see Reply::NeedPartsLibrary). It has already forgotten its copy, so the next sync_parts_library reinstalls; the caller must re-submit the run. Never true for a runner that shares the caller’s store.

fn poll_run(&mut self) -> Option<RunReply>

Non-blocking: the next completed run reply, if any (drained each frame).

fn submit_query(&mut self, query: MeasureQuery)

Submit a per-object measurement query (answered against the runner’s warm registry). Inline computes it immediately; a thread impl computes it on the runner thread and surfaces it via poll_query.

fn poll_query(&mut self) -> Option<MeasureReply>

Non-blocking: the next completed measurement reply, if any.

fn submit_mesh_import(&mut self, request: MeshImportRequest)

Submit RANSAC mesh reconstruction to the runner’s thread/worker.

fn poll_mesh_import(&mut self) -> Option<MeshImportReply>

Non-blocking: the next completed mesh reconstruction, if any.

fn submit_step_probe(&mut self, request: StepProbeRequest)

Submit a STEP product-structure probe (see StepProbeRequest).

fn poll_step_probe(&mut self) -> Option<StepProbeReply>

Non-blocking: the next completed STEP probe, if any.

fn poll_progress(&mut self) -> Option<RunProgress>

Non-blocking: the MOST RECENT progress report of the in-flight run, with any older ones discarded (only the latest feature matters). None for a synchronous runner — Inline has finished before anyone could ask.

fn reset(&mut self)

Drop the delta baseline (document switch → full rebuild).
