Module protocol_resource_adapter 

Protocol resource adapters for GPIO, I2C, and SPI.

Provides representative hardware backends and fakes for protocol-backed resources (Spec 8.1, 9.5, 11.6; Milestone P4). Protocol resources preserve their production request/response semantics rather than being flattened into generic byte writes or MMIO offsets.

Structs

FakeClock

In-memory fake Clock for tests.

FakeGpio

In-memory fake GPIO pin for tests.

FakeI2c

In-memory fake I2C device for tests.

FakeReset

In-memory fake Reset for tests.

FakeSerial

In-memory fake Serial for tests.

FakeSpi

In-memory fake SPI device for tests.

Enums

DeviceBackend

Unified enum backend allowing heterogeneous resources to coexist in one proxy instance.

Traits

ClockBackend

Hardware access abstraction for a Clock device.

GpioBackend

Hardware access abstraction for a GPIO pin.

I2cBackend

Hardware access abstraction for an I2C bus device.

ResetBackend

Hardware access abstraction for a Reset device.

ResourceBackend

Unified hardware access trait covering MMIO and protocol resources.

SerialBackend

Hardware access abstraction for a Serial device.

SpiBackend

Hardware access abstraction for a SPI bus device.
