Crate pixelflow_test_support 

Deterministic test helpers for PixelFlow filters, plugins, and embedders.

Helpers here avoid external media files by constructing frames and graph sources fully in memory.

Structs

GoldenTolerance

Absolute per-sample tolerance for deterministic golden-frame comparisons.

SyntheticClip

Renderable in-memory synthetic clip plus its executor map.

TraceEvent

One scheduler trace event.

TraceGate

Deterministic gate used to force one frame to finish after another starts.

TracePassthroughFilter

Passthrough filter that records dependency requests and commit ordering.

TraceRecorder

Thread-safe recorder for scheduler trace events.

TraceSource

Source executor that records prepare ordering and tags frame metadata.

Enums

TraceEventKind

Kind of scheduler event recorded by trace executors.

Constants

EXACT_GOLDEN_TOLERANCE

Exact comparison tolerance for structural filters such as crop and trim.
