Struct Channel 

pub struct Channel {
    pub id: ChannelId,
    pub transport: TransportProtocol,
    pub communication_info: HashMap<String, String>,
    pub status: ChannelStatus,
    pub created_at: u64,
    pub role: SenderKind,
    pub replica_id: Option<u64>,
}

A channel — the post-pairing representation of a peer.

Stored by crate::protocol::DeRecChannelStore and returned by its channels() method.

Serialize / Deserialize are derived for the FFI and WASM bridges, which ship channels to host languages as JSON over the language boundary. Library consumers writing a Rust DeRecChannelStore see only the typed value and never observe the serde representation; the wire format is not part of the public API and may change independently. #[serde(default)] annotations let bridges decode legacy bytes that predate later-added fields without erroring.

Fields

id: ChannelId

Unique identifier for this channel.

transport: TransportProtocol

The peer’s transport endpoint.

communication_info: HashMap<String, String>

Application-level identity metadata for the peer on this channel.

Free-form key/value pairs — the protocol treats this as opaque and never inspects keys or values. Anything an app wants to remember about who is on the other end (display name, account id, avatar URI, …) lives here. App-level identity logic (e.g. auto-linking by display name) reads from this map; the protocol does not.

On the initiator side, this is whatever the caller supplied when starting crate::protocol::DeRecFlow::Pairing. On the responder side, it is the peer’s own communication_info extracted from the wire pair-request — the same map that surfaces in crate::protocol::DeRecEvent::PairingCompleted::peer_communication_info.

status: ChannelStatus

Lifecycle status. Messages on Pending channels are ignored.

created_at: u64

Unix timestamp (seconds) when the channel was created.

role: SenderKind

This node’s role on this channel, fixed at pairing time.

The orchestrator enforces flow directionality against this value: an Owner may initiate ProtectSecret / VerifyShares / Discovery / RecoverSecret; a Helper may not. Inbound messages are gated the other way around — a StoreShareRequest is only honored on a channel where this node is the Helper, and so on.

replica_id: Option<u64>

The peer’s replica identity, populated only when role is ReplicaSource or ReplicaDestination.

Extracted from the peer’s derec.replica_id entry in CommunicationInfo during the pair handshake. None on Helper/Owner channels and as a defensive default on freshly-paired Replica channels where the peer did not advertise one.
