Enum CalError 

pub enum CalError {
    NoReferenceClock,
    UnsupportedCounter,
    UnstableCounter,
    NoProgress,
}

Why calibration refused the hardware counter.

Variants

NoReferenceClock

No reference monotonic clock is available (neither std nor libc features).

UnsupportedCounter

The architecture has no supported counter (the tsc feature is on, but this is not x86_64/aarch64), or the invariant/frequency check failed.

UnstableCounter

Two bracketed measurements disagreed beyond tolerance — the counter is not constant-rate (or the machine is wildly noisy).

NoProgress

The measurement window made no progress (a dead counter).
