Enum HdrOutputFormat 

#[non_exhaustive]
pub enum HdrOutputFormat {
    LinearFloat,
    LinearF16,
    Srgb8,
}

Output format for HDR reconstruction.

Mirrors libultrahdr’s three supported decode outputs:

• LinearFloat ↔ UHDR_IMG_FMT_64bppRGBAHalfFloat semantically (same linear-light content), but at f32 precision instead of f16. Use when downstream wants float math.
• LinearF16 ↔ UHDR_IMG_FMT_64bppRGBAHalfFloat exactly. Use for direct compositor / GPU-texture handoff.
• Srgb8 ↔ UHDR_IMG_FMT_32bppRGBA8888 with sRGB transfer. Use when downstream wants SDR (display_boost = 1.0 typical).

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

LinearFloat

Linear f32 RGBA where 1.0 = SDR white (203 nits). Range [0, ~display_boost]. 16 bytes/pixel (RgbaF32).

LinearF16

Linear f16 (IEEE 754 half-precision) RGBA where 1.0 = SDR white. 8 bytes/pixel (RgbaF16). Mirrors libultrahdr’s UHDR_IMG_FMT_64bppRGBAHalfFloat.

Srgb8

sRGB 8-bit (SDR output, no HDR boost). 4 bytes/pixel (Rgba8).

Trait Implementations

impl Clone for HdrOutputFormat

fn clone(&self) -> HdrOutputFormat

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for HdrOutputFormat

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

Formats the value using the given formatter.

impl PartialEq for HdrOutputFormat

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