Interface: PortLike

Defined in: src/batteries/isolation/types.ts:313

The minimal message-passing duck the wire protocol (protocol.ts) is built over. A Worker / MessagePort (post = postMessage, onMessage wraps addEventListener('message', ...)) and a Node ChildProcess / process (post = .send, onMessage wraps .on('message', ...)) both satisfy this structurally — the shared protocol is exercised against linked in-memory fake ports; the browser and Node transports wire it to the real transports.
