Enum TransferFunction 

#[non_exhaustive]
pub enum TransferFunction {
    TraditionalGammaSdr,
    TraditionalGammaHdr,
    SmpteSt2084Pq,
    Bt2100Hlg,
}

Source-side electro-optical transfer function.

The integer values are the kernel’s enum hdmi_eotf. That enum is kernel-internal, so the mapping is restated here to keep it stable for userspace; TransferFunction::as_u8 is the only place it is applied.

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.

TraditionalGammaSdr

BT.1886 / sRGB.

TraditionalGammaHdr

Traditional gamma, HDR range.

SmpteSt2084Pq

SMPTE ST 2084 (PQ) – HDR10 and HDR10+.

Bt2100Hlg

BT.2100 hybrid log-gamma.
