Struct screen_layer::Layer

pub struct Layer { /* fields omitted */ }

Represents a layer.

Implementations

impl Layer

pub fn new(top_left: Vec2<isize>, len: Vec2<usize>) -> 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

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

Formats the value using the given formatter.

impl Default for Layer

pub fn default() -> Layer

Returns the "default value" for a type.

impl Eq for Layer

impl Hash for Layer

pub fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

pub fn hash_slice<H>(data: &[Self], state: &mut H) where
    H: Hasher, 

Feeds a slice of this type into the given Hasher.

impl Index<usize> for Layer

Layer can index into each pixels.

type Output = Vec<Option<RGB8>>

None represents the pixel is transparent.

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

Performs the indexing (container[index]) operation.

impl IndexMut<usize> for Layer

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

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

impl PartialEq<Layer> for Layer

pub fn eq(&self, other: &Layer) -> bool

This method tests for self and other values to be equal, and is used by ==.

pub fn ne(&self, other: &Layer) -> bool

This method tests for !=.
