Struct StatsLedger 

pub struct StatsLedger { /* private fields */ }

The shared traffic ledger.

Lock-free and const-constructible, so a board declares one static and hands out &'static references to every producer and reader. Ordering is Relaxed throughout: each counter is independent, no reader is deciding anything from the ordering between two of them, and the alternative buys a fence on the radio’s hot path to make diagnostics agree about an instant nobody is looking at.

Implementations

impl StatsLedger

pub const fn new() -> Self

pub fn bump(&self, counter: Counter)

Record one event.

pub fn add(&self, counter: Counter, n: u32)

Record n events. Adding zero is free and is the ordinary case for a mirroring producer whose source has not moved.

pub fn get(&self, counter: Counter) -> u32

What a host reads: events since boot, or since it last cleared this counter.

pub fn raw(&self, counter: Counter) -> u32

The underlying tally, ignoring any clear. Nothing on the wire reports this; it is here so a device that wants a since-boot view of its own has one.

pub fn reset(&self, counter: Counter)

Start this counter over from here.

Clearing several counters is several of these, so a frame landing mid-sweep is counted before one and after another. Nothing reads them closely enough for that to matter, and the alternative is a lock on the radio’s hot path.
