Struct ConsumerCounterSelection 

pub struct ConsumerCounterSelection {
    pub events_consumed: bool,
    pub consumer_empty_spins: bool,
    pub consumer_lag_max: bool,
}

Select which consumer-side counters are attached to a shared counters file.

The full set is appropriate for normal observability. Targeted microbenchmarks can deliberately narrow the set to reduce hot-path perturbation while still exposing the counters required for a specific experiment.

Fields

events_consumed: bool

Attach the monotonic events_consumed counter.

consumer_empty_spins: bool

Attach the consumer_empty_spins counter.

consumer_lag_max: bool

Attach the consumer_lag_max high-water-mark counter.

Implementations

impl ConsumerCounterSelection

pub const FULL: Self

Full RFC-0040 consumer counter set.

pub const LITE: Self

Minimal consumer counter set for experiments that only need consumption progress.
