}

Defines the requests that can be sent to core. Drivers don’t use this type directly. They are indirectly used by RequestChan.

Variants

AddReadonlyDevice

Registers a read-only device with core.

The reply is a pair where the first element is a channel to report updated values of the device. The second element, if not None, is the last saved value of the device.

Fields

driver_name: Name

dev_name: Name

dev_units: Option<String>

max_history: Option<usize>

rpy_chan: Sender<Result<ReportReading>>

AddReadWriteDevice

Registers a writable device with core.

The reply is a 3-tuple where the first element is a channel to report updated values of the device. The second element is a stream that yileds incoming settings to the device. The last element, if not None, is the last saved value of the device.

Fields

driver_name: Name

dev_name: Name

dev_units: Option<String>

max_history: Option<usize>

rpy_chan: Sender<Result<(ReportReading, RxDeviceSetting, Option<Value>)>>
