Enum GatewayCarrier 

Source 
pub enum GatewayCarrier {
    Internet,
    Reticulum,
}
Expand description

A carrier that speaks the gateway contract, and can therefore answer about a third party’s reachability.

Two of the five transports qualify, and the type exists so the other three cannot be passed where a gateway answer is expected. That is not a theoretical tidiness: every effect of a presence answer is carrier-scoped, so a wrong carrier records a fact against a transport that never claimed it and pins an un-park flush to a transport that never proved anything, neither of which fails loudly.

  • BLE and Wi-Fi Direct are zone carriers. A neighbour being in range is a fact about this device’s own link, not a claim about a third party, and it arrives through discovery rather than through a verb.
  • Nostr structurally cannot answer: a broadcast relay reports no per-recipient delivery, so it is a carrier and never a gateway. See ADR 0017. This is a permanent gap, recorded here in the type so it stops being rediscovered as a bug.

Variants§

§

Internet

The internet relay, which implemented every verb before the contract named them.

§

Reticulum

A gateway daemon reached over the Reticulum transport’s local IP contract.

Implementations§

Source§

impl GatewayCarrier

Source

pub fn transport(self) -> TransportType

The transport this gateway’s answers are recorded against.

Source

pub fn presence_source(self) -> PresenceSource

How a presence answer from this gateway is labelled to the app.

Source

pub fn from_transport(transport: TransportType) -> Option<Self>

The gateway behind transport, or None for a carrier that answers no verdicts.

Exhaustive by construction rather than by a wildcard: a sixth transport must be classified here deliberately, and the wrong default is the silent one. A carrier that returns None is not broken; it simply never contradicts the blanket “up means reachable” assumption, which is the residual docs/mesh.md records.

fn quirk(&self, value: Quirk) -> Painted<&T>
