Crate frp_engine 

frp engine — graph execution runtime for the infinite-db frp backend.

Provides:

• Graph — the live container that holds blocks, edges, atoms, and port values and drives the execution loop.
• Executor — evaluates a single edge against the current port-value map.
• Scheduler — decides which edges fire and when (OnChange / OnTick / OnEvent).
• [toposort] — Kahn’s algorithm for ordering edges by data dependency.
• TransformRegistry / eval_transform — named and inline transforms.
• EngineError — unified error type.

Modules

error

Error types for the frp-engine crate.

executor

Edge executor — collects input values, runs the transform, and writes outputs.

graph

Graph — the live container that ties together blocks, edges, atoms, port values, scheduling, and execution.

scheduler

Edge scheduler — tracks which edges should fire and when.

toposort

Topological sort (Kahn’s algorithm) over a set of HyperEdges.

transform

Named transform registry and edge transform evaluation.
