Struct Mirror 

pub struct Mirror { /* private fields */ }

A mirror of a monotone tally kept somewhere else.

Producers that copy someone else’s counters — the MAC’s, the PHY’s — hold one of these per source field and feed the ledger the difference since the last pass, so the ledger only ever sees additions. A source that goes backwards (a counter reconstructed, a peripheral restarted) contributes nothing rather than a nonsensical jump.

Implementations

impl Mirror

pub const fn new() -> Self

pub fn advance( &mut self, ledger: &StatsLedger, counter: Counter, now: u32, ) -> u32

Fold the source’s current value in, returning what was added.
