Enum RoundTripTickOutcome 

pub enum RoundTripTickOutcome {
    Ongoing,
    Complete(f64),
    TimedOut,
}

Result of processing a single input sample through RoundTripMeasurementState::tick.

The session loop calls tick for every sample that arrives on the input ring buffer and acts on the returned outcome to decide whether to continue, finish, or abort.

Variants

Ongoing

The measurement is still in progress; more input samples are required.

Complete(f64)

All IMPULSE_COUNT echoes were detected successfully.

Contains the arithmetic mean of the individual round-trip durations in milliseconds.

TimedOut

The current impulse timed out before an echo was detected.

This usually means the output is not physically routed back to the input, or the signal level is too low to cross the derived threshold.
