Configuration governing whether and how the node forwards received frames.

The UMSH MAC layer includes an optional built-in repeater that forwards packets it successfully receives, extending the effective range of the network without requiring dedicated infrastructure. RepeaterConfig controls every facet of that behavior:

• enabled — master on/off switch. When false, all inbound forwarding logic is skipped even if the other fields are populated.
• regions — a local list of 2-byte ARNCE region codes used as the flood-forwarding eligibility filter. When non-empty, packets carrying region codes are flood-forwarded only if at least one of those codes appears here; when empty, forwarding imposes no region check and a tagged packet is forwarded whatever its region.
• default_region — the region code inserted into a flood-forwarded packet that carries none. None — the default — means the repeater never tags: untagged packets are forwarded untagged. Tagging is deliberately opt-in and independent of regions, because inserting a code asserts where the packet is, not merely which regions the repeater will carry. An already-tagged packet is always forwarded with its codes unchanged.
• min_rssi / min_snr — signal-quality thresholds for flood forwarding. Packets received below these values are not flood-forwarded; this prevents marginal receptions from being re-injected into the network at full power, which would degrade SNR for nearby nodes rather than help. These thresholds do not apply to source-routed hops.
• Flood contention tuning — controls the SNR-to-delay mapping used when several eligible repeaters contend to flood-forward the same frame. These values should usually remain aligned across the mesh.
• amateur_radio_mode — determines whether the repeater may forward encrypted or blind-unicast frames, and whether it must inject a station callsign. See AmateurRadioMode.
• station_callsign — the ARNCE/HAM-64 callsign injected into the options block of every forwarded frame when operating in LicensedOnly or Hybrid mode, satisfying the third-party identification requirements of FCC §97.119 and equivalent regulations.

The default configuration has enabled: false; repeating must be explicitly opted in.

Fields

enabled: bool

Whether repeater forwarding is enabled.

regions: Vec<[u8; 2], 8>

Allowed repeater region codes. Empty imposes no region check.

default_region: Option<[u8; 2]>

Region code inserted into an untagged flood-forwarded packet. None forwards untagged packets untagged.

min_rssi: Option<i16>

Minimum RSSI threshold for flood forwarding.

min_snr: Option<i8>

Minimum SNR threshold for flood forwarding.

flood_contention_snr_low_db: i8

Lower clamp bound for SNR-based flood forwarding contention.

flood_contention_snr_high_db: i8

Upper clamp bound for SNR-based flood forwarding contention.

flood_contention_min_window_percent: u8

Minimum forwarding contention window as a percentage of T_frame.

flood_contention_max_window_frames: u8

Maximum forwarding contention window as a multiple of T_frame.

flood_contention_ack_guard_percent: u8

ACK protection interval as a percentage of T_frame, added to the contention delay when flood-forwarding an ack-requested packet that was received with no remaining source-route hops (see channel-access.md § ACK Protection Interval).

flood_contention_max_deferrals: u8

Maximum number of overheard-repeat deferrals before abandoning a pending forward.

amateur_radio_mode: AmateurRadioMode

Amateur-radio operating mode for forwarding.

station_callsign: Option<HamAddr>

Optional station callsign injected on forwarded traffic.

Trait Implementations

impl Clone for RepeaterConfig

fn clone(&self) -> RepeaterConfig

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RepeaterConfig

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

Formats the value using the given formatter.

impl Default for RepeaterConfig

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq for RepeaterConfig

fn eq(&self, other: &RepeaterConfig) -> 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.
