Struct SDL_GPUBlendOp 

#[repr(transparent)]
pub struct SDL_GPUBlendOp(pub c_int);

Specifies the operator to be used when pixels in a render target are blended with existing pixels in the texture.

The source color is the value written by the fragment shader. The destination color is the value currently existing in the texture.

Availability

This enum is available since SDL 3.2.0.
