Enum BlendPreset 

#[non_exhaustive]
pub enum BlendPreset {
    Opaque,
    AlphaBlend,
    PremultipliedAlpha,
    Additive,
    Multiply,
}

Common blend mode presets.

Examples

use mabda::blend::{BlendPreset, blend_state};

let state = blend_state(BlendPreset::AlphaBlend);
let opaque = blend_state(BlendPreset::Opaque);

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.

Opaque

No blending — source overwrites destination.

AlphaBlend

Standard alpha blending: src * src_alpha + dst * (1 - src_alpha).

PremultipliedAlpha

Premultiplied alpha: src + dst * (1 - src_alpha). Use when source colors are pre-multiplied by alpha.

Additive

Additive blending: src + dst. No alpha modulation. Good for glow, particles, light accumulation.

Multiply

Multiply blending: src * dst. Darkens the destination by the source color.

Trait Implementations

impl Clone for BlendPreset

fn clone(&self) -> BlendPreset

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for BlendPreset

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

Formats the value using the given formatter.

impl Hash for BlendPreset

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 BlendPreset

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