Struct AV1LayeredImageIndexing 

pub struct AV1LayeredImageIndexing {
    pub layer_sizes: [u32; 3],
}

AV1 layered image indexing from the a1lx property box.

Provides byte sizes for the first 3 layers so decoders can seek to a specific layer without parsing the full bitstream. See AVIF § 4.3.6.

Fields

layer_sizes: [u32; 3]

Byte sizes of layers 0, 1, 2. The last layer’s size is implicit (total item size minus the sum of these three).

Trait Implementations

impl Clone for AV1LayeredImageIndexing

fn clone(&self) -> AV1LayeredImageIndexing

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AV1LayeredImageIndexing

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

Formats the value using the given formatter.

impl PartialEq for AV1LayeredImageIndexing

fn eq(&self, other: &AV1LayeredImageIndexing) -> 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.
