以下是该枚举的定义：
typedef enum D3D12_PIPELINE_STATE_SUBOBJECT_TYPE {
D3D12_PIPELINE_STATE_SUBOBJECT_TYPE_ROOT_SIGNATURE,
D3D12_PIPELINE_STATE_SUBOBJECT_TYPE_VS,
D3D12_PIPELINE_STATE_SUBOBJECT_TYPE_PS,
D3D12_PIPELINE_STATE_SUBOBJECT_TYPE_DS,
D3D12_PIPELINE_STATE_SUBOBJECT_TYPE_HS,
D3D12_PIPELINE_STATE_SUBOBJECT_TYPE_GS,
D3D12_PIPELINE_STATE_SUBOBJECT_TYPE_CS,
D3D12_PIPELINE_STATE_SUBOBJECT_TYPE_STREAM_OUTPUT,
D3D12_PIPELINE_STATE_SUBOBJECT_TYPE_BLEND,
D3D12_PIPELINE_STATE_SUBOBJECT_TYPE_SAMPLE_MASK,
D3D12_PIPELINE_STATE_SUBOBJECT_TYPE_RASTERIZER,
D3D12_PIPELINE_STATE_SUBOBJECT_TYPE_DEPTH_STENCIL,
D3D12_PIPELINE_STATE_SUBOBJECT_TYPE_INPUT_LAYOUT,
D3D12_PIPELINE_STATE_SUBOBJECT_TYPE_IB_STRIP_CUT_VALUE,
D3D12_PIPELINE_STATE_SUBOBJECT_TYPE_PRIMITIVE_TOPOLOGY,
D3D12_PIPELINE_STATE_SUBOBJECT_TYPE_RENDER_TARGET_FORMATS,
D3D12_PIPELINE_STATE_SUBOBJECT_TYPE_DEPTH_STENCIL_FORMAT,
D3D12_PIPELINE_STATE_SUBOBJECT_TYPE_SAMPLE_DESC,
D3D12_PIPELINE_STATE_SUBOBJECT_TYPE_NODE_MASK,
D3D12_PIPELINE_STATE_SUBOBJECT_TYPE_CACHED_PSO,
D3D12_PIPELINE_STATE_SUBOBJECT_TYPE_FLAGS,
D3D12_PIPELINE_STATE_SUBOBJECT_TYPE_DEPTH_STENCIL1,
D3D12_PIPELINE_STATE_SUBOBJECT_TYPE_VIEW_INSTANCING,
D3D12_PIPELINE_STATE_SUBOBJECT_TYPE_MAX_VALID,
} D3D12_PIPELINE_STATE_SUBOBJECT_TYPE;
这个枚举定义了许多不同的子对象类型，每个类型对应于管线状态中的不同组件。例如，D3D12_PIPELINE_STATE_SUBOBJECT_TYPE_ROOT_SIGNATURE 表示根签名（root signature）子对象，D3D12_PIPELINE_STATE_SUBOBJECT_TYPE_VS 表示顶点着色器（vertex shader）子对象，以此类推。
在创建管线状态时，您将使用这些子对象类型来指定所需的管线状态配置。
