Struct Capabilities 

pub struct Capabilities {
    pub protocol: Option<Protocol>,
    pub ty: Option<Type>,
    pub model: Option<String>,
    pub commands: Vec<u8>,
    pub ms_whql: Option<u8>,
    pub mccs_version: Option<Version>,
    pub vcp_features: BTreeMap<FeatureCode, VcpDescriptor>,
    pub edid: Option<EdidData>,
    pub vdif: Vec<VdifData>,
    pub unknown_tags: Vec<UnknownTag>,
}

Parsed display capabilities string.

Fields

protocol: Option<Protocol>

The protocol class.

It’s not very clear what this field is for.

ty: Option<Type>

The type of display.

model: Option<String>

The model name/number of the display.

commands: Vec<u8>

A list of the supported VCP commands.

ms_whql: Option<u8>

A value of 1 seems to indicate that the monitor has passed Microsoft’s Windows Hardware Quality Labs testing.

mccs_version: Option<Version>

Monitor Command Control Set version code.

vcp_features: BTreeMap<FeatureCode, VcpDescriptor>

Virtual Control Panel feature code descriptors.

edid: Option<EdidData>

Extended Display Identification Data

Note that although the standard defines this field, in practice it is not used and instead the EDID is read from a separate I2C EEPROM on the monitor.

vdif: Vec<VdifData>

Video Display Information Format are optional extension blocks for the EDID. Like the EDID field, this is probably not in use.

unknown_tags: Vec<UnknownTag>

Additional unrecognized data from the capability string.

Trait Implementations

impl Clone for Capabilities

fn clone(&self) -> Capabilities

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Capabilities

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for Capabilities

fn default() -> Capabilities

Returns the “default value” for a type.

impl Hash for Capabilities

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for Capabilities

fn cmp(&self, other: &Capabilities) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for Capabilities

fn eq(&self, other: &Capabilities) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for Capabilities

fn partial_cmp(&self, other: &Capabilities) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.
