From 7fdffdda630ee61ae0e09ef8f1ace52bbf70e2b0 Mon Sep 17 00:00:00 2001 From: Danilo Krummrich Date: Mon, 25 May 2026 22:20:51 +0200 Subject: rust: driver: decouple driver private data from driver type Add a type Data<'bound> associated type to all bus driver traits, decoupling the driver's bus device private data type from the driver struct itself. In the context of adding a 'bound lifetime, making this an associated type has the advantage that it allows us to avoid a driver trait global lifetime and it avoids the need for ForLt for bus device private data; both of which make the subsequent implementation by buses much simpler. All existing drivers and doc examples set type Data = Self to preserve the current behavior.
