Struct graphics::DrawState

pub struct DrawState {
    pub primitive: Primitive,
    pub multi_sample: Option<MultiSample>,
    pub scissor: Option<Rect>,
    pub stencil: Option<Stencil>,
    pub depth: Option<Depth>,
    pub blend: Option<Blend>,
    pub color_mask: ColorMask,
}

An assembly of states that affect regular draw calls

Fields

primitive	How to rasterize geometric primitives.
multi_sample	Multi-sampling mode
scissor	Scissor mask to use. If set, no pixel outside of this rectangle (in screen space) will be written to as a result of rendering.
stencil	Stencil test to use. If None, no stencil testing is done.
depth	Depth test to use. If None, no depth testing is done.
blend	Blend function to use. If None, no blending is done.
color_mask	Color mask to use. Each flag indicates that the given color channel can be written to, and they can be OR'd together.

Methods

impl DrawState

fn new() -> DrawState

Create a default DrawState. Uses counter-clockwise winding, culls the backface of each primitive, and does no scissor/stencil/depth/blend/color masking.

fn get_target_mask(&self) -> Mask

Return a target mask that contains all the planes required by this state.

fn multi_sample(self) -> DrawState

Enable multi-sampled rasterization

fn stencil(self, fun: Comparison, value: u8) -> DrawState

Set the stencil test to a simple expression

fn depth(self, fun: Comparison, write: bool) -> DrawState

Set the depth test with the mask

fn scissor(self, x: u16, y: u16, w: u16, h: u16) -> DrawState

Set the scissor

fn blend(self, preset: BlendPreset) -> DrawState

Set the blend mode to one of the presets
