Struct HdrStaticMetadata 

#[non_exhaustive]
pub struct HdrStaticMetadata {
    pub eotf: HdrEotf,
    pub static_metadata_descriptors: u8,
    pub max_luminance: Option<f32>,
    pub max_fall: Option<f32>,
    pub min_luminance: Option<f32>,
}

Decoded HDR Static Metadata Data Block (extended tag 0x06).

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.

eotf: HdrEotf

Supported EOTFs (tone-mapping curves).

static_metadata_descriptors: u8

Static Metadata Descriptor type bitmap (usually bit 0 = Type 1 / MaxCLL/MaxFALL).

max_luminance: Option<f32>

Desired content maximum luminance in cd/m², decoded from byte 3.

Encoded as 50 × 2^(raw / 32). None when the byte is absent.

max_fall: Option<f32>

Desired content maximum frame-average light level (MaxFALL) in cd/m².

Same encoding as max_luminance. None when absent.

min_luminance: Option<f32>

Desired content minimum luminance in cd/m², decoded from byte 5.

Encoded as max_luminance × (raw / 255)² / 100. None when absent or when max_luminance is not present.

Implementations

impl HdrStaticMetadata

pub fn new( eotf: HdrEotf, static_metadata_descriptors: u8, max_luminance: Option<f32>, max_fall: Option<f32>, min_luminance: Option<f32>, ) -> Self

Constructs an HdrStaticMetadata.

Trait Implementations

impl Clone for HdrStaticMetadata

fn clone(&self) -> HdrStaticMetadata

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for HdrStaticMetadata

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

Formats the value using the given formatter.

impl PartialEq for HdrStaticMetadata

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