Enum PixelLayer 

pub enum PixelLayer {
    Backdrop,
    Background,
    Sprite,
}

Which layer won the priority decision at a pixel.

Variants

Backdrop

Neither layer was opaque: the universal backdrop ($3F00), or the palette-address override the PPU applies when rendering is disabled with v pointing into palette space.

Background

The background pattern won.

Sprite

A sprite won — either because the background pixel was transparent or because the sprite had front priority.

Trait Implementations

impl Clone for PixelLayer

fn clone(&self) -> PixelLayer

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PixelLayer

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

Formats the value using the given formatter.

impl Default for PixelLayer

fn default() -> PixelLayer

Returns the “default value” for a type.

impl Hash for PixelLayer

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 PixelLayer

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