Traits

Ddc

A high level interface to DDC commands.

DdcCommand

A (slightly) higher level interface to DdcCommandRaw.

DdcCommandMarker

Using this marker trait will automatically implement the Ddc and DdcTable traits.

DdcCommandRaw

Allows the execution of arbitrary low level DDC commands.

DdcCommandRawMarker

Using this marker trait will automatically implement the DdcCommand trait.

DdcHost

A DDC host is able to communicate with a DDC device such as a display.

DdcTable

Table commands can read and write arbitrary binary data to a VCP feature.

Eddc

E-DDC allows reading extensions of Enhanced EDID.

Edid

A trait that allows retrieving Extended Display Identification Data (EDID) from a device.
