};

Defined in: packages/common/src/Worker.ts:91

Opaque type for platform-specific native MessagePort.

Exists because postMessage transfer requires the native object itself, not a wrapper. Ensures type-safe wiring between MessagePort.native and CreateMessagePort without exposing platform details.
