Enum BlendMode 

pub enum BlendMode {
    Over,
    Add,
    Multiply,
}

Blending operation applied when compositing a surface onto the back buffer.

Variants

Over

Standard alpha-over compositing (Porter-Duff SRC_OVER).

Add

Additive blending: dst + src * alpha (clamped to 255).

Multiply

Multiplicative blending: (dst * src) / 255.

Trait Implementations

impl Clone for BlendMode

fn clone(&self) -> BlendMode

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for BlendMode

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

Formats the value using the given formatter.

impl Default for BlendMode

fn default() -> BlendMode

Returns the “default value” for a type.

impl PartialEq for BlendMode

fn eq(&self, other: &BlendMode) -> 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 Copy for BlendMode

impl Eq for BlendMode

impl StructuralPartialEq for BlendMode
