Enum Alpha 

pub enum Alpha {
    Premultiplied,
    NotPremultiplied,
    DontCare,
}

Variants

Premultiplied

NotPremultiplied

DontCare

This is used for opaque textures for which the presence of alpha in the output data format does not matter.

Implementations

impl Alpha

pub const fn from_premultiplied(is_premultiplied: bool) -> Self

pub const fn needs_alpha_multiplication(&self) -> bool

Trait Implementations

impl Clone for Alpha

fn clone(&self) -> Alpha

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Alpha

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Alpha

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl MallocSizeOf for Alpha

fn size_of(&self, ops: &mut MallocSizeOfOps) -> usize

Measure the heap usage of all descendant heap-allocated structures, but not the space taken up by the value itself.

impl PartialEq for Alpha

fn eq(&self, other: &Alpha) -> 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 Alpha

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 Alpha

impl Eq for Alpha

impl StructuralPartialEq for Alpha
