pub use crate::compression::Compression;

block_type_strings	The string literals used to represent a `BlockType` in a file.
type_names	Contains string literals identifying the type of an attribute.

ChannelDescription	A single channel in an layer. Does not contain the actual pixel data, but instead merely describes it.
ChannelList	A List of channels. Channels must be sorted alphabetically.
Chromaticities	The color space of the pixels.
FloatRect	A rectangular section anywhere in 2D float space.
IntegerBounds	A rectangular section anywhere in 2D integer space.
KeyCode	Uniquely identifies a motion picture film frame.
Preview	A small `rgba` image of `i8` values that approximates the real exr image.
Text	A byte array with each byte being a char. This is not UTF an must be constructed from a standard string.
TileDescription	Describes how the layer is divided into tiles. Specifies the size of each tile in the image and whether this image contains multiple resolution levels.
TimeCode	Contains time information.

AttributeValue	Contains one of all possible attributes. Includes a variant for custom attributes.
BlockType	layer type, specifies block type and deepness.
EnvironmentMap	If this attribute is present, it describes how this texture should be projected onto an environment.
LevelMode	Whether to also store increasingly smaller versions of the original image.
LineOrder	In what order the `Block`s of pixel data appear in a file.
SampleType	The type of samples in this channel.

byte_size	Number of bytes this attribute would consume in an exr file.
read	Read the attribute without validating. The result may be `Ok` even if this single attribute is invalid.
validate	Validate this attribute.
write	Without validation, write this attribute to the byte stream.

DataWindow	The integer rectangle describing where an layer is placed on the infinite 2D global space.
DisplayWindow	The integer rectangle limiting which part of the infinite 2D global space should be displayed.
Matrix3x3	A float matrix with three rows and three columns.
Matrix4x4	A float matrix with four rows and four columns.
Rational	An integer dividend and divisor, together forming a ratio.
TextSlice	A byte slice, interpreted as text
