Enum ColorModel 

#[non_exhaustive]
pub enum ColorModel {
    Gray,
    GrayAlpha,
    Rgb,
    Rgba,
    Cmyk,
    Bilevel,
    Indexed,
}

The colour interpretation of a pixel’s channels.

Distinguishes layouts that share a channel count: ColorModel::Rgba and ColorModel::Cmyk are both four channels but must never be interchanged, and ColorModel::Gray, ColorModel::Bilevel, and ColorModel::Indexed are all one channel with different meanings.

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

Single luminance channel.

GrayAlpha

Luminance plus an alpha channel.

Rgb

Red, green, blue.

Rgba

Red, green, blue, alpha (unassociated).

Cmyk

Cyan, magenta, yellow, black ink separations.

Bilevel

One channel, 0 = black and any non-zero value = white (a 1-bit image carried as one byte per pixel).

Indexed

One channel of indices into a separate colour palette.

Trait Implementations

impl Clone for ColorModel

fn clone(&self) -> ColorModel

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for ColorModel

impl Debug for ColorModel

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

Formats the value using the given formatter.

impl Eq for ColorModel

impl Hash for ColorModel

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, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for ColorModel

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