Trait Surface

    fn set_texel(&mut self, x: u32, y: u32, value: Self::Texel);

So-so display surface trait for reuse purposes.

Required Associated Types

type Texel

Specific texel type.

Required Methods

fn texel(&self, x: u32, y: u32) -> Option<Self::Texel>

Get texel given its coordinates.

fn set_texel(&mut self, x: u32, y: u32, value: Self::Texel)

Set texel given its coordinates.

fn clear(&mut self, value: Self::Texel)

Clear the surface with the given color.

fn width(&self) -> u32

Get surface width.

fn height(&self) -> u32

Get surface height.

Provided Methods

unsafe fn texel_unchecked(&self, x: u32, y: u32) -> Self::Texel

Get texel given its coordinates unsafely.

Safety

• x must be in range [0, width - 1];
• y must be in range [0, height - 1];

unsafe fn set_texel_unchecked(&mut self, x: u32, y: u32, value: Self::Texel)

Set texel value given its coordinates unsafely.

Safety

• x must be in range [0, width - 1];
• y must be in range [0, height - 1];
