Struct MasteringDisplay 

pub struct MasteringDisplay {
    pub primaries_r_x: u16,
    pub primaries_r_y: u16,
    pub primaries_g_x: u16,
    pub primaries_g_y: u16,
    pub primaries_b_x: u16,
    pub primaries_b_y: u16,

}

HDR10 Mastering Display Color Volume per SMPTE ST 2086 / HEVC SEI message 137 (D.2.28 in the H.265 spec) / AV1 Metadata OBU METADATA_TYPE_HDR_MDCV. Wire-encoded into the MP4 mdcv box as 8 × u16 BE primaries/white-point + 2 × u32 BE luminance, total 24 bytes payload.

Units (per the spec):

• primaries_*_x / primaries_*_y / white_point_* are in increments of 0.00002 of the CIE 1931 chromaticity diagram. The wire format is the unscaled u16 (e.g. BT.2020 red x=0.708 → (0.708 / 0.00002) = 35400).
• max_luminance and min_luminance are in increments of 0.0001 cd/m² (nits). The wire format is the unscaled u32 (e.g. 1000 nits → 10_000_000).

Field-name contract with Squad-21 (probe HDR): these names are load-bearing — the probe imports this struct and populates it directly from the SEI/OBU payload. Do not rename without coordinating.

Trait Implementations

impl Clone for MasteringDisplay

fn clone(&self) -> MasteringDisplay

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for MasteringDisplay

impl Debug for MasteringDisplay

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

Formats the value using the given formatter.

impl Eq for MasteringDisplay

impl PartialEq for MasteringDisplay

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