Struct exr::image::read::layers::AllLayersReader

pub struct AllLayersReader<ChannelsReader> {
    layer_readers: SmallVec<[LayerReader<ChannelsReader>; 2]>,
}

Processes pixel blocks from a file and accumulates them into a list of layers. For example, ChannelsReader can be [SpecificChannelsReader] or [AnyChannelsReader<FlatSamplesReader>].

Fields

layer_readers: SmallVec<[LayerReader<ChannelsReader>; 2]>

Trait Implementations

impl<ChannelsReader: Clone> Clone for AllLayersReader<ChannelsReader>

fn clone(&self) -> AllLayersReader<ChannelsReader>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<ChannelsReader: Debug> Debug for AllLayersReader<ChannelsReader>

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

Formats the value using the given formatter.

impl<C> LayersReader for AllLayersReader<C>

where C: ChannelsReader,

type Layers = SmallVec<[Layer<<C as ChannelsReader>::Channels>; 2]>

The type of resulting layers

fn filter_block( &self, _: &MetaData, tile: TileCoordinates, block: BlockIndex, ) -> bool

Specify whether a single block of pixels should be loaded from the file

fn read_block( &mut self, headers: &[Header], block: UncompressedBlock, ) -> UnitResult

Load a single pixel block, which has not been filtered, into the reader, accumulating the layer

fn into_layers(self) -> Self::Layers

Deliver the final accumulated layers for the image

impl<ChannelsReader: PartialEq> PartialEq for AllLayersReader<ChannelsReader>

fn eq(&self, other: &AllLayersReader<ChannelsReader>) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
