Struct DrawBuilder

pub struct DrawBuilder<'a, T: 'a> { /* private fields */ }

A rectangle builder.

Obtained from Renderer::rect() or Renderer::fill()

Implementations

impl<'a, T> DrawBuilder<'a, T>

The following implementations are available when drawing with Renderer::rect() or Renderer::fill().

pub fn color(self, color: Color) -> Self

Sets a color for drawing. Defaults to white. If a texture is supplied in addtion to the color, each fragment will be computed from texel color * color.

pub fn texture(self, texture: &'a Texture) -> Self

Sets the texture for drawing. If a color is supplied in addtion to the texture, each fragment will be computed from texel color * color.

pub fn blendmode(self, blendmode: BlendMode) -> Self

Sets the blendmode used to blend the source with the target.

pub fn program(self, program: &'a Program) -> Self

Sets the fragment shader program used to draw.

pub fn model_matrix(self, model_matrix: [[f32; 4]; 4]) -> Self

Sets a model matrix for drawing.

pub fn draw(self)

Draws the rectangle.

impl<'a> DrawBuilder<'a, DrawBuilderRect>

The following implementations are only available when drawing with Renderer::rect()

pub fn view_matrix(self, view_matrix: [[f32; 4]; 4]) -> Self

Sets a view matrix for drawing.

pub fn view_target(self) -> Self

Uses a view matrix that maps the dimensions of the target to the pixel-size of the target.

This is the default setting. It means that a point, e.g. (12., 34.) is mapped to the pixel (12, 34) on the target.

pub fn view_display(self) -> Self

Uses a view matrix that maps the dimensions of the display to the pixel-size of the target.

pub fn view_source(self) -> Self

Uses a view matrix that maps the dimensions of the source to the pixel-size of the target.

pub fn view_one(self) -> Self

Uses a matrix that maps the entire target to a rectangle of (0., 0., 1., 1.)

Trait Implementations

impl<'a, T: Clone + 'a> Clone for DrawBuilder<'a, T>

fn clone(&self) -> DrawBuilder<'a, T>

Returns a copy of the value.

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

Performs copy-assignment from source.
