Actor Handlers

Handlers implement client methods inside actor context.

The simplest handler pattern is actor-bound.

 
export const handleMove = handler(
  GameClient.definition.external.Move,
  Effect.fn(function* ({ position }) {
    const { currentClient, name: gameId } = yield* TicTacToeActor
    const { player } = yield* currentClient.attachments
 
    yield* TicTacToeActor.all.send("MoveMade", { player, position })
    yield* saveMove(gameId, player, position)
  }),
)

handler(method, implementation) is a typed pass-through. It returns the handler unchanged at runtime but narrows its payload, success, and failure types to the supplied method.
