Struct ReleaseErrors 

#[non_exhaustive]
pub struct ReleaseErrors {
    pub count: u64,
    pub p50_ns: u64,
    pub p95_ns: u64,
    pub max_ns: u64,
}

Observed lateness of deferred releases, in one session.

Measured end to end — from the unit’s release_at to the instant its bytes were handed to the destination stream — so it includes the wheel, the runtime wake and the engine, which is what a caller actually cares about. A sample taken inside the release thread would have reported 0.55 ms while the object went out at 0.9 ms.

Values are bucketed with two significant bits per octave, so each quantile is the upper bound of its bucket and is accurate to within 25%; max_ns is exact.

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.

count: u64

Deferred units released. Units written inline (never queued) and units flushed by a drain that ignores release times are excluded, so this is the number of units that actually waited.

p50_ns: u64

Median lateness, nanoseconds (bucket upper bound).

p95_ns: u64

95th-percentile lateness, nanoseconds (bucket upper bound).

max_ns: u64

Worst lateness, nanoseconds. Exact.
