Enum RoundTripMeasurementPhase 

pub enum RoundTripMeasurementPhase {
    Idle,
    CalibrationAmbient,
    WaitingForEcho(usize),
}

High-level phases of the RoundTripMeasurementState state machine.

The machine progresses linearly through these phases on each measurement session:

CalibrationAmbient  →  WaitingForEcho(0)  →  WaitingForEcho(1)  →  …  →  Idle

It never transitions backwards. Once Idle is reached the session loop exits.

Variants

Idle

The measurement has concluded (either successfully or via timeout).

The session loop writes silence to the output and exits on the next iteration.

CalibrationAmbient

The state machine is consuming ambient input samples to estimate the noise floor.

No impulses are emitted during this phase. Transitions to WaitingForEcho(0) once CALIBRATION_SAMPLES have been processed.

WaitingForEcho(usize)

An impulse has been (or is about to be) emitted and the state machine is listening for its return on the input.

The usize payload is the zero-based index of the current impulse (0 … IMPULSE_COUNT − 1). On a successful echo detection the index advances and the machine stays in this variant; after the last echo it transitions to Idle.

Trait Implementations

impl Clone for RoundTripMeasurementPhase

fn clone(&self) -> RoundTripMeasurementPhase

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for RoundTripMeasurementPhase

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for RoundTripMeasurementPhase

fn eq(&self, other: &RoundTripMeasurementPhase) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
