Enum ChannelLayout 

#[non_exhaustive]
#[repr(u8)]
pub enum ChannelLayout {
    Gray = 1,
    GrayAlpha = 2,
    Rgb = 3,
    Rgba = 4,
    Bgra = 5,
    Oklab = 6,
    OklabA = 7,
}

Channel layout (number and meaning of channels).

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Gray = 1

Single luminance channel.

GrayAlpha = 2

Luminance + alpha.

Rgb = 3

Red, green, blue.

Rgba = 4

Red, green, blue, alpha.

Bgra = 5

Blue, green, red, alpha (Windows/DirectX byte order).

Oklab = 6

Oklab perceptual color: L, a, b.

OklabA = 7

Oklab perceptual color with alpha: L, a, b, alpha.

Implementations

impl ChannelLayout

pub const fn channels(self) -> usize

Number of channels in this layout.

pub const fn has_alpha(self) -> bool

Whether this layout includes an alpha channel.

Trait Implementations

impl Clone for ChannelLayout

fn clone(&self) -> ChannelLayout

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ChannelLayout

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

Formats the value using the given formatter.

impl Display for ChannelLayout

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

Formats the value using the given formatter.

impl Hash for ChannelLayout

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

where __H: Hasher,

Feeds this value into the given Hasher.

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

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for ChannelLayout

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