Enum HdrEncoding 

pub enum HdrEncoding {
    ExtendedLinear,
    Pq,
}

HDR encoding the composite shader emits on the EDR path. Drives both the swapchain colour-space choice (CAMetalLayer on Metal, SetColorSpace1 on DirectX) and the shader’s per-pixel encode.

Variants

ExtendedLinear

Pass linear extended-range values through. Swapchain colour space is kCGColorSpaceExtendedLinearDisplayP3; the OS compositor handles the final encode to whatever the panel needs. 1.0 = SDR reference white; values above drive the panel’s headroom.

Pq

PQ-encode (SMPTE ST 2084) the linear scene before write. Swapchain colour space is kCGColorSpaceDisplayP3_PQ; the panel decodes via the PQ EOTF. Suitable for HDR10 / HDR1000 monitors that prefer PQ-encoded values directly. SDR reference white maps to 203 nits per ITU-R BT.2408.
