Events emitted by the modem loop to the consumer via super::AsyncModem::next_event.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Version(VersionResponse)

Modem firmware version + capabilities (one-shot, typically at init).

Status(ModemStatus)

Modem status update — periodic (from internal 250 ms poll) OR unsolicited (from the modem itself after TX transitions etc.).

Ack

Positive acknowledgement for a sent command.

Fields

command: u8

The command byte the modem ACK’d.

Nak

Negative acknowledgement for a sent command.

Fields

command: u8

The command byte the modem rejected.

reason: NakReason

The reason the modem gave.

DStarHeaderRx

D-STAR header received from the radio’s MMDVM TX (41 bytes).

Fields

bytes: [u8; 41]

The 41 raw header bytes.

DStarDataRx

D-STAR voice data received from the radio (9 AMBE + 3 slow data = 12 bytes).

Fields

bytes: [u8; 12]

The 12 raw voice-frame bytes.

DStarLost

D-STAR signal lost from the radio side.

DStarEot

D-STAR end-of-transmission from the radio side.

Debug

Debug text from the modem firmware (MMDVM_DEBUG1..DEBUG5).

Fields

level: u8

Debug level (1..=5).

text: String

Decoded UTF-8 text (NUL-trimmed, lossy where needed).

SerialData(Vec<u8>)

Serial passthrough data from the modem.

TransparentData(Vec<u8>)

Transparent data from the modem.

UnhandledResponse

The modem sent a mode we don’t fully model yet (DMR/YSF/P25/NXDN/POCSAG/FM), but the raw frame was accepted — payload preserved verbatim.

Fields

command: u8

The command byte.

payload: Vec<u8>

The raw payload bytes.

TransportClosed

The transport closed gracefully (e.g. serial device unplug).

Trait Implementations

impl Clone for Event

fn clone(&self) -> Event

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Event

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

Formats the value using the given formatter.
