Enum ImageMaskMode 

#[non_exhaustive]
pub enum ImageMaskMode {
    A,
    B,
    G,
    R,
    Luminance,
}

Defines how the A8 image mask pixels are to be derived from a source mask image.

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.

A

Alpha channel.

If the image has no alpha channel masks by Luminance.

B

Blue channel.

If the image has no color channel fallback to monochrome channel, or A.

G

Green channel.

If the image has no color channel fallback to monochrome channel, or A.

R

Red channel.

If the image has no color channel fallback to monochrome channel, or A.

Luminance

Relative luminance.

If the image has no color channel fallback to monochrome channel, or A.

Trait Implementations

impl Clone for ImageMaskMode

fn clone(&self) -> ImageMaskMode

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ImageMaskMode

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

Formats the value using the given formatter.

impl Default for ImageMaskMode

fn default() -> ImageMaskMode

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for ImageMaskMode

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Hash for ImageMaskMode

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 ImageMaskMode

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

impl Serialize for ImageMaskMode

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Copy for ImageMaskMode

impl Eq for ImageMaskMode
