}

Display parameters decoded from DisplayID 2.x block 0x21.

Contains factory-calibrated colorimetry (12-bit chromaticity), HDR luminance levels, color depth, display technology, and gamma. Luminance values are transmitted on-wire as IEEE 754 half-precision (f16) and converted to f32 by the decoder before storage. Image size and pixel count are exposed separately on DisplayCapabilities via preferred_image_size_mm and native_pixels.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

chromaticity: Chromaticity12

Factory-calibrated chromaticity for the three primaries and white point.

color_space_cie1976: bool

true if chromaticity values use CIE 1976 (u’, v’) coordinates; false (default) for CIE 1931 (x, y).

max_luminance_full: Option<f32>

Maximum luminance at full-screen coverage in cd/m². None if not specified.

max_luminance_10pct: Option<f32>

Maximum luminance at 10% screen coverage in cd/m². None if not specified.

min_luminance: Option<f32>

Minimum luminance in cd/m². None if not specified.

luminance_guidance: bool

true if non-zero luminance values are source guidance rather than guaranteed minima.

color_bit_depth: Option<u8>

Color bit depth per channel (6, 8, 10, 12, 14, or 16). None if not defined.

display_technology: DisplayTechnology

Display technology decoded from byte 10 of block 0x21.

gamma: Option<f32>

Gamma EOTF in range 1.00–3.54. None if unspecified (stored byte 0xFF).

scan_orientation: ScanOrientation

Scan orientation decoded from bits 2:0 of byte 11 of block 0x21.

audio_external: bool

true if audio output uses an external jack rather than integrated speakers.

Trait Implementations

impl Clone for DisplayParamsV2

fn clone(&self) -> DisplayParamsV2

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DisplayParamsV2

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

Formats the value using the given formatter.

impl Default for DisplayParamsV2

fn default() -> DisplayParamsV2

Returns the “default value” for a type.

impl PartialEq for DisplayParamsV2

fn eq(&self, other: &DisplayParamsV2) -> 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.
