Struct exr::meta::attributes::ChannelList

pub struct ChannelList {
    pub list: SmallVec<[Channel; 5]>,
    pub bytes_per_pixel: usize,
}

A List of channels. Channels must be sorted alphabetically.

Fields

list: SmallVec<[Channel; 5]>

The channels in this list.

bytes_per_pixel: usize

The number of bytes that one pixel in this image needs.

Methods

impl ChannelList

pub fn new(channels: SmallVec<[Channel; 5]>) -> Self

Does not validate channel order.

impl ChannelList

pub fn byte_size(&self) -> usize

Number of bytes this would consume in an exr file.

pub fn write(&self, write: &mut impl Write) -> PassiveResult

Without validation, write this instance to the byte stream. Assumes channels are sorted alphabetically and all values are validated.

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

Read the value without validating.

pub fn validate(&self, allow_sampling: bool, strict: bool) -> PassiveResult

Check if channels are valid and sorted.

Trait Implementations

impl Clone for ChannelList

fn clone(&self) -> ChannelList

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ChannelList

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

Formats the value using the given formatter.

impl Eq for ChannelList

impl PartialEq<ChannelList> for ChannelList

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

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

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

This method tests for !=.
