Struct RenderPipelineDesc 

pub struct RenderPipelineDesc<'a, D: Device> {
    pub label: &'static str,
    pub layouts: &'a [Option<&'a D::BindGroupLayout>],
    pub shader: &'a D::ShaderModule,
    pub vs_entry: &'static str,
    pub fs_entry: Option<&'static str>,
    pub color_targets: &'a [ColorTarget],
    pub depth: Option<DepthState>,
    pub topology: PrimitiveTopology,
    pub constants: &'a [(&'static str, f64)],
}

Everything needed to create a render pipeline. Pipelines are created at load and cached; never inside the frame loop.

Fields

label: &'static str

Debug label.

layouts: &'a [Option<&'a D::BindGroupLayout>]

Bind-group layouts by group index (0 = per-frame, 1 = per-pass, 2 = per-representation, 3 = per-material); None leaves a frequency slot unused without renumbering the groups after it.

shader: &'a D::ShaderModule

The compiled module holding both entry points; modules are created once and shared across the pipelines that use them.

vs_entry: &'static str

Vertex entry point name.

fs_entry: Option<&'static str>

Fragment entry point name; None for depth-only pipelines.

color_targets: &'a [ColorTarget]

Color targets, in attachment order.

depth: Option<DepthState>

Depth behavior, if the pass has a depth attachment.

topology: PrimitiveTopology

Primitive assembly.

constants: &'a [(&'static str, f64)]

Values for the shader’s override constants, by identifier.

Specializing at pipeline creation is what lets a shader resolve a shape, a sample count or a feature switch once, instead of branching on it in every fragment. Empty leaves every override at its default.

Trait Implementations
