mccs_version: Option<Version>

MCCS VCP version code.

mccs_database: Database

MCCS VCP feature information.

Methods

impl DisplayInfo

pub fn new(backend: Backend, id: String) -> Self

Create an empty DisplayInfo.

pub fn from_edid(
    backend: Backend,
    id: String,
    edid_data: Vec<u8>
) -> Result<Self>

Creates a new DisplayInfo from unparsed EDID data.

May fail to parse the EDID data.

pub fn from_capabilities(
    backend: Backend,
    id: String,
    caps: &Capabilities
) -> Self

Create a new DisplayInfo from parsed capabilities.

pub fn update_from(&mut self, info: &DisplayInfo)

Merge in any missing information from another DisplayInfo

pub fn update_from_ddc<D: Ddc>(&mut self, ddc: &mut D) -> Result<(), D::Error>

Populate information from a DDC connection.

This will read the VCP Version (0xdf) and fill in the mccs_database. This data will be incomplete compared to being filled in from a capability string.
