Enum conrod_wgpu::RenderPassCommand

pub enum RenderPassCommand<'a> {
    SetScissor {
        top_left: [u32; 2],
        dimensions: [u32; 2],
    },
    Draw {
        vertex_range: Range<u32>,
    },
    SetBindGroup {
        bind_group: &'a BindGroup,
    },
    SetPipeline {
        pipeline: &'a RenderPipeline,
    },
}

A draw command that maps directly to the wgpu::CommandEncoder method. By returning RenderPassCommands, we can avoid consuming the entire AutoCommandBufferBuilder itself which might not always be available from APIs that wrap Vulkan.

Variants

SetScissor

Fields

top_left: [u32; 2]

dimensions: [u32; 2]

Specify the rectangle to which drawing should be cropped.

Draw

Fields

vertex_range: Range<u32>

Draw the specified range of vertices.

SetBindGroup

Fields

bind_group: &'a BindGroup

A new image requires drawing and in turn a new bind group requires setting.

SetPipeline

Fields

pipeline: &'a RenderPipeline

An image requiring a different bind group layout requires drawing and in turn, we must set the necessary render pipeline.
