Struct MrftEngine 

pub struct MrftEngine { /* private fields */ }

The MRFT relay-feedback state machine. Construct with MrftEngine::new, then call MrftEngine::step once per PV sample.

Deliberately has no knowledge of --mrftDelayTime pre/post padding: the caller decides when to start calling step() at all, rather than the engine accepting an internal “delay active” no-op flag. That keeps this type’s only job “given a PV sample, decide whether to switch” — nothing else.

Implementations

impl MrftEngine

pub fn new( config: LoopConfig, direction: ControllerDirection, beta: f32, initial: InitialReadings, start_time: DateTime<Utc>, compat: MrftCompat, ) -> MrftEngine

Builds a new engine and performs the one-time setup MRFTstart does before the relay-switching loop begins: resolves the action multiplier from direction, clamps the relay amplitude to the MV range, and seeds the peak/trough trackers from the initial PV reading.

start_time seeds time_previous_switch (TimePreviousSwitch = DateTime.Now in the legacy MRFTinitializeVariables) — pass the timestamp of the first Tick that will be given to step, or whatever timestamp the caller considers “test start”.

beta is the hysteresis multiplier for this (process type, controller type) combination — see crate::constants::lookup. It is response-level-invariant, so any crate::constants::ResponseLevel passed to lookup yields the same beta.

pub fn step(&mut self, tick: Tick) -> Vec<Action>

Feeds one PV sample through the engine. Returns the actions the caller must perform: zero or one Action::WriteMv (mirrors MRFTswitchIsNeeded + MRFTperformSwitch), followed by Action::Complete at most once, on the tick that satisfies the completion condition.

Calling step again after Complete has been returned is a no-op that returns an empty Vec — the engine has nothing left to do.

pub fn state(&self) -> MrftState

A snapshot of the fields a golden-master comparison checks per tick.

pub fn is_complete(&self) -> bool

Whether the completion condition has been reached. Pure port of MRFTisComplete.
