Overview ¶

Package ingress defines an in-process typed identifier for the origin of an RX frame flowing through the modem-RX fanout.

Source provenance is threaded alongside *pb.ReceivedFrame so downstream subscribers (KISS broadcast, digipeater, APRS submit) can suppress feedback loops when a frame originated from a KISS-TNC interface rather than the local modem. The identity is deliberately kept in-process — it is not encoded on the wire protocol.

Types ¶

type Kind ¶

type Kind uint8

Kind enumerates the supported RX sources. New sources (SDR, AGW, Bluetooth TNC, etc.) get their own constant without churning the fanout signature.

const (
	// KindModem is a frame demodulated by the local modem bridge.
	KindModem Kind = iota + 1
	// KindKissTnc is a frame ingested from a KISS interface configured
	// in TNC mode (i.e. an off-air RX source, not a TX peer).
	KindKissTnc
)

type Source ¶

type Source struct {
	Kind Kind
	ID   uint32
}

Source identifies where an RX frame entered graywolf. ID is the KissInterface DB row ID for KindKissTnc; unused (zero) for KindModem.

func KissTnc ¶

func KissTnc(ifaceID uint32) Source

KissTnc returns a Source tagging a frame as coming from the KISS-TNC interface with the given DB row ID.

func Modem ¶

func Modem() Source

Modem returns a Source tagging a frame as coming from the local modem.

func (Source) IsKissTnc ¶

func (s Source) IsKissTnc(id uint32) bool

IsKissTnc reports whether this Source is the KISS-TNC interface with the given ID. Used by the broadcast subscriber to suppress echo back to the originating interface.
