Struct ClassCounters 

pub(crate) struct ClassCounters {
    name: String,
    bytes_delivered: AtomicU64,
    bytes_dropped: AtomicU64,
    objects_delivered: AtomicU64,
    objects_dropped: AtomicU64,
    tokens_exhausted_episodes: AtomicU64,
    blocked_episodes: AtomicU64,
    starved_behind_other_class: AtomicU64,
}

One class’s atomic counters — the storage behind one ClassStats.

name is immutable for the recorder’s lifetime, so it is a plain String rather than anything shared: the class list cannot change under a running session.

Implementations

impl ClassCounters

fn named(name: String) -> Self

An all-zero row labelled name.

fn snapshot(&self) -> ClassStats

Read this row.

fn reset(&self)

Zero every counter, keeping the row’s name.

Only ProxyRecorder resets: a session’s figures are the session’s for its whole life. Seven relaxed stores, and deliberately not one atomic swap of the whole row — there is no such primitive, and a reset that raced traffic would land between two fetch_adds whatever it was written with. What that costs is a snapshot straddling a reset that reports a row part-cleared, which is why the reset is a caller’s verb and not something this crate does on its own.
