ContactKey

value class ContactKey(val value: String)(source)

Type-safe wrapper for contact key strings (channel index + node address).

Properties

val address: NodeAddress

Parsed NodeAddress for the contact.

val addressString: String

The node address portion: everything after the channel digit, or the whole key when there is no channel prefix. Empty if the key is empty.

val channel: Int

The channel index (first character). Returns 0 if the key is empty or has no channel digit.

val channelOrNull: Int?

The channel index if the key carries a leading channel digit, or null for a legacy unprefixed direct-message key. Callers that must distinguish "channel 0" from "no channel prefix" (e.g. PKI vs legacy DM routing) need this rather than channel.
