		help
		This option enables the safe Rust abstraction layer for the PWM
		subsystem. It provides idiomatic wrappers and traits necessary for
		writing PWM controller drivers in Rust.

		The abstractions handle resource management (like memory and reference
		counting) and provide safe interfaces to the underlying C core,
		allowing driver logic to be written in safe Rust.
