Struct SDL_BlendFactor 

#[repr(transparent)]
pub struct SDL_BlendFactor(pub c_uint);

The normalized factor used to multiply pixel components.

The blend factors are multiplied with the pixels from a drawing operation (src) and the pixels from the render target (dst) before the blend operation. The comma-separated factors listed above are always applied in the component order red, green, blue, and alpha.

Available Since: This enum is available since SDL 3.2.0.

Trait Implementations

impl Clone for SDL_BlendFactor

fn clone(&self) -> SDL_BlendFactor

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SDL_BlendFactor

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

Formats the value using the given formatter.

impl Hash for SDL_BlendFactor

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 SDL_BlendFactor

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