Struct Layer

pub struct Layer { /* private fields */ }

Represents a layer.

Implementations

impl Layer

pub fn new(top_left: Vec2<i32>, len: Vec2<u32>) -> Self

Creates an instance of this struct.

top_left, len, and top_left + len can be negative, or larger than the resolution of the screen. In such cases, parts that does not fit in the screen will not be drawn.

Trait Implementations

impl Debug for Layer

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

Formats the value using the given formatter.

impl Default for Layer

fn default() -> Layer

Returns the “default value” for a type.

impl Hash for Layer

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 Index<usize> for Layer

Layer can index into each pixels.

type Output = [Option<Rgb<u8>>]

None represents the pixel is transparent.

fn index(&self, index: usize) -> &Self::Output

Performs the indexing (container[index]) operation.

impl IndexMut<usize> for Layer

fn index_mut(&mut self, index: usize) -> &mut Self::Output

Performs the mutable indexing (container[index]) operation.

impl PartialEq for Layer

fn eq(&self, other: &Layer) -> 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 Eq for Layer
