Struct ShapeRenderer 

pub struct ShapeRenderer { /* private fields */ }

helps to draw basic BasicShapes

Implementations

impl ShapeRenderer

pub fn new(device: &Device, config: &SurfaceConfiguration) -> ShapeRenderer

creates a new ShapeRenderer which can render BasicShape. these can be created with ShapeRenderer::rect, ShapeRenderer::oval

can be reused with ShapeRenderer::clear function

pub fn render<'a, 'b: 'a>( &'b self, encoder: &mut CommandEncoder, texture_view: &TextureView, device: &Device, )

renders the current BasicShapes which can be added with ShapeRenderer::rect, ShapeRenderer::oval, …

pub fn clear(&mut self)

clears the current drawn BasicShapes which can be added with ShapeRenderer::rect, ShapeRenderer::oval, …

pub fn set_frame_size(&mut self, frame_size: (f32, f32)) -> &mut Self

sets the current frame_size

pub fn frame_size(&self) -> (f32, f32)

frame_size.0 is the with in which BasicShape get displayed.

frame_size.1 is the height in which BasicShape get displayed

(0,0) -> center of screen

pub fn set_frame_offset(&mut self, frame_offset: (f32, f32)) -> &mut Self

sets the current frame_offset

pub fn frame_offset(&self) -> (f32, f32)

frame_offset are values which get added to all BasicShape

pub fn resize( &mut self, device: &Device, config: &SurfaceConfiguration, ) -> &mut Self

resizes the depthBuffer should be called on every window resize

pub fn background_color(&mut self, background_color: Color) -> &mut Self

sets the clearColor/ backgroundColor

pub fn rect(&mut self) -> &mut Rect

renders Rect and returns a Ref to it

pub fn oval(&mut self) -> &mut Oval

renders Oval and returns a Ref to it

pub fn image(&mut self, texture_index: usize) -> &mut Image

renders Image and returns a Ref to it

pub fn add_texture_from_bytes( &mut self, bytes: &[u8], device: &Device, queue: &Queue, ) -> &mut Self

pub fn add_textures_from_bytes( &mut self, bytes: &Vec<&[u8]>, device: &Device, queue: &Queue, ) -> &mut Self

adds a texture to the usable texturePool
