channels
INFO
Анықтаманың өзі ағылшын тілінде: ол WIT файлдарынан автоматты түрде жасалады.
Named byte channels between mods, and between a server mod and its client half. Local delivery works since 0.2 (messages are queued and delivered on the next poll or tick, never during send); the network targets travel as 0xBC CHANNEL packets from milestone M5 and report unsupported until then.
