Struct OutputSignaling 

#[non_exhaustive]
pub struct OutputSignaling {
    pub colorspace: Option<Colorspace>,
    pub hdr_metadata: Option<HdrSourceMetadata>,
    pub hdr_downgraded: bool,
}

What the scene wants declared on the connector for one frame.

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.

colorspace: Option<Colorspace>

The Colorspace to write, or None to leave the property alone.

None when no layer said what it was in. Writing a guess would override whatever the last client left, which on a connector is sticky.

hdr_metadata: Option<HdrSourceMetadata>

The metadata to publish, or None for no HDR signaling.

hdr_downgraded: bool

Whether HDR was called for and could not be carried.

The layers asked for it and the connector cannot: no HDR_OUTPUT_METADATA, or no max bpc that reaches 10. The metadata is dropped rather than sent, and this says so – a caller that wants to tone-map itself, or tell the user, has no other way to find out.
