Struct DisplayCoarseRange 

pub struct DisplayCoarseRange {
    pub high_dynamic_range: Option<bool>,
    pub gamut: Option<DisplayGamut>,
}

Coarse, boolean dynamic-range and gamut signal.

This is the only luminance-adjacent data the web exposes, and a useful cross-check on other platforms.

Fields

high_dynamic_range: Option<bool>

CSS @media (dynamic-range: high): the display can present HDR-range content. Best-effort and platform-defined — “capable”, not “an HDR mode is active”. It feeds tone_map_headroom: Some(false) marks a definitively-SDR display, collapsing the headroom to 1.0.

gamut: Option<DisplayGamut>

Best gamut bucket the display covers (CSS color-gamut).

Trait Implementations

impl Clone for DisplayCoarseRange

fn clone(&self) -> DisplayCoarseRange

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DisplayCoarseRange

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

Formats the value using the given formatter.

impl Default for DisplayCoarseRange

fn default() -> DisplayCoarseRange

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for DisplayCoarseRange

fn deserialize<__D>( __deserializer: __D, ) -> Result<DisplayCoarseRange, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for DisplayCoarseRange

fn eq(&self, other: &DisplayCoarseRange) -> 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 Serialize for DisplayCoarseRange

fn serialize<__S>( &self, __serializer: __S, ) -> Result<<__S as Serializer>::Ok, <__S as Serializer>::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
