Struct RlcController 

pub struct RlcController { /* private fields */ }

Immediate-up / conservative-down controller for the RLC parameters. It raises protection (coding on, smaller step, larger window, denser coefficients) the instant the sensors call for it - cheap insurance against loss - but only lowers it after hold consecutive ticks that all want less, so a brief quiet spell does not strip protection. Turning coding OFF entirely (disable-on-clean) is the riskiest de-escalation, so it needs the longer clean_hold sustained-clean window, exactly as the block-RS policy guards the drop to Passthrough.

Implementations

impl RlcController

pub fn new(window: u16, step: u16, dt: u8, hold: u32) -> Self

A controller starting from active coding at the given parameters, with hold lower-demand ticks required before relaxing a knob and 4 * hold sustained-clean ticks before disabling coding entirely.

pub fn with_holds( window: u16, step: u16, dt: u8, hold: u32, clean_hold: u32, ) -> Self

Like new but with an explicit clean_hold.

pub fn set_rtt_ms(&mut self, rtt_ms: f32)

Set the measured round trip (ms), which scales the rate-law margin.

pub fn set_latency_floor(&mut self)

Enable the latency-priority floor at the current baseline step: the controller never relaxes FEC lighter than this (nor disables coding), so an isolated loss always has an in-window repair and never falls to an ARQ round trip that stalls in-order delivery. The controller may still escalate HEAVIER under high loss. Call once at construction, before any feedback.

pub fn current(&self) -> RlcDecision

The current coding configuration.

pub fn decide(&mut self, s: &SensorSnapshot) -> RlcDecision

Fold one channel assessment and return the configuration to apply.
