Struct LatencyMetrics 

#[non_exhaustive]
pub struct LatencyMetrics {
    pub interval: Duration,
    pub last: Duration,
    pub histogram: Histogram,
    pub last_sample: Option<Instant>,
    pub stalls: u64,
    pub stall_duration: Duration,
    pub stalled: bool,
}

Snapshot of an arbiter’s scheduling latency.

The arbiter runs a task that sleeps for interval and records how late it wakes up. Lateness includes the time the runtime spent running other tasks and handling driver events, and the timer’s own wake-up latency.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

interval: Duration

Sampling interval.

last: Duration

Lateness of the most recent sample.

histogram: Histogram

Lateness of all samples.

last_sample: Option<Instant>

Time of the most recent sample, None if no sample has been recorded.

A time much older than interval means the arbiter is blocked.

stalls: u64

Number of stalls detected by the watchdog.

An arbiter is stalled when it has not recorded a sample for longer than interval plus the ping_threshold.

stall_duration: Duration

Total duration of finished stalls.

stalled: bool

Whether the arbiter is currently stalled.
