Struct GlRenderStateInit 

pub struct GlRenderStateInit {
    pub depth: GlDepthState,
    pub blend: GlBlendState,
    pub cull: GlCullState,
    pub color_mask: GlColorMask,
    pub scissor: Option<GlScissor>,
    pub viewport: GlViewport,
}

Constructor inputs for GlRenderState.

GlRenderState::context_defaults is the only way to build one today, and it hard-codes the state a freshly created GL context happens to be in. Every other state — a depth-tested draw, a scissored viewport, a masked render target — has to be assembled field by field to reach WebGl2Backend::apply_state, which means it cannot be built from outside the crate. Naming the inputs closes that gap.

Fields

depth: GlDepthState

The depth-test state.

blend: GlBlendState

The blend state.

cull: GlCullState

The culling and winding state.

color_mask: GlColorMask

Which channels the fragment stage may write.

scissor: Option<GlScissor>

The scissor rectangle, or None when scissoring is off.

viewport: GlViewport

The viewport rectangle.
