| 21 | * Internal convenience only -- never part of the public API. The one | ||
| 22 | * contract every device family must actually satisfy is | ||
| 23 | * EcApp::FactoryFn (ecapp/Factory.h), which takes every construction | ||
| 24 | * parameter directly, no bundling struct. SlaveContext exists purely | ||
| 25 | * so a family's own factory lambda (and its adapter constructor) | ||
| 26 | * doesn't have to repeat that same long parameter list by hand; | ||
| 27 | * wrapFactory() adapts a SlaveContext-taking lambda to the real, | ||
| 28 | * struct-free FactoryFn the Registry expects. | ||
