Struct exr::meta::Requirements

pub struct Requirements {
    pub file_format_version: u8,
    pub is_single_layer_and_tiled: bool,
    pub has_long_names: bool,
    pub has_deep_data: bool,
    pub has_multiple_layers: bool,
}

A summary of requirements that must be met to read this exr file. Used to determine whether this file can be read by a given reader. It includes the OpenEXR version number. This library aims to support version 2.0.

Fields

file_format_version: u8

This library supports reading version 1 and 2, and writing version 2.

is_single_layer_and_tiled: bool

If true, this image has tiled blocks and contains only a single layer. If false and not deep and not multilayer, this image is a single layer image with scan line blocks.

has_long_names: bool

Whether this file has strings with a length greater than 31. Strings can never be longer than 255.

has_deep_data: bool

This image contains at least one layer with deep data.

has_multiple_layers: bool

Whether this file contains multiple layers.

Implementations

impl Requirements

pub fn is_multilayer(&self) -> bool

Is this file declared to contain multiple layers?

pub fn read<R: Read>(read: &mut R) -> Result<Self>

Read the value without validating.

pub fn write<W: Write>(self, write: &mut W) -> UnitResult

Without validation, write this instance to the byte stream.

pub fn validate(&self) -> UnitResult

Validate this instance.

Trait Implementations

impl Clone for Requirements

fn clone(&self) -> Requirements

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Requirements

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

Formats the value using the given formatter.

impl Hash for Requirements

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H) where
    H: Hasher, 

Feeds a slice of this type into the given Hasher.

impl PartialEq<Requirements> for Requirements

fn eq(&self, other: &Requirements) -> bool

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

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

This method tests for !=.
