Enum ImageAlphaType 

#[repr(u8)]
pub enum ImageAlphaType {
    Alpha = 0,
    AlphaPremultiplied = 1,
}

Handling of alpha channel.

Variants

Alpha = 0

Image has separate alpha channel (also called straight/unpremultiplied alpha).

AlphaPremultiplied = 1

Image has colors with premultiplied alpha.

Trait Implementations

impl CheckedBitPattern for ImageAlphaType

type Bits = u8

Self must have the same layout as the specified Bits except for the possible invalid bit patterns being checked during is_valid_bit_pattern.

fn is_valid_bit_pattern(bits: &u8) -> bool

If this function returns true, then it must be valid to reinterpret bits as &Self.

impl Clone for ImageAlphaType

fn clone(&self) -> ImageAlphaType

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Contiguous for ImageAlphaType

const MIN_VALUE: u8

The lower inclusive bound for valid instances of this type.

const MAX_VALUE: u8

The upper inclusive bound for valid instances of this type.

type Int = u8

The primitive integer type with an identical representation to this type.

fn from_integer(value: Self::Int) -> Option<Self>

If value is within the range for valid instances of this type, returns Some(converted_value), otherwise, returns None.

fn into_integer(self) -> Self::Int

Perform the conversion from C into the underlying integral type. This mostly exists otherwise generic code would need unsafe for the value as integer

impl Debug for ImageAlphaType

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

Formats the value using the given formatter.

impl PartialEq for ImageAlphaType

fn eq(&self, other: &ImageAlphaType) -> 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 Zeroable for ImageAlphaType

fn zeroed() -> Self

Calls zeroed.

impl Copy for ImageAlphaType

impl Eq for ImageAlphaType

impl NoUninit for ImageAlphaType

impl StructuralPartialEq for ImageAlphaType
