Spanda

spanda-interpreter

Tree-walking interpreter and simulator — executes typed Spanda programs.

Layout

Runtime lives under src/runtime/ (~21 modules):

• orchestrator.rs — main execution loop
• runtime_eval.rs, runtime_execute.rs — expression and statement evaluation
• runtime_scheduler.rs, runtime_triggers.rs — tasks and triggers
• runtime_robot.rs, runtime_sensors.rs, runtime_navigation.rs — robot surface
• simulator.rs — physics-lite 2D backend
• Domain hooks delegate to workspace crates (spanda-safety, spanda-comm, spanda-hal, …)

Public API

• run_program — execute a parsed Program
• Interpreter, InterpreterOptions, RobotBackend, SimRobotBackend
• Re-exported by spanda-driver::run and spanda_core::run

Dependencies

Imports workspace crates directly (no spanda-core). CoreRuntimeHost in spanda-runtime-host implements RuntimeHost for connectivity, fleet, and transport wiring.
