Vertex Descriptor Conversions

Most Metal rendering pipelines need an MTLVertexDescriptor. MetalSupport provides converters from several source types so you can get there from wherever you're starting:

                 MDLVertexDescriptor
                       │
                       ▼
MTLFunction ──▶ MTLVertexDescriptor ◀──▶ VertexDescriptor
                    ▲         ▲
                    │         │
          [MTLVertexAttribute]   Swift struct (reflection)

| From | To | How | |------|----|-----| | VertexDescriptor | MTLVertexDescriptor | MTLVertexDescriptor(descriptor) or .mtlVertexDescriptor | | MTLVertexDescriptor | VertexDescriptor | VertexDescriptor(mtlDescriptor) | | MDLVertexDescriptor | MTLVertexDescriptor | MTLVertexDescriptor(mdlDescriptor) | | MDLVertexFormat | MTLVertexFormat | MTLVertexFormat(mdlFormat) | | MTLDataType | MTLVertexFormat | MTLVertexFormat(dataType) | | [MTLVertexAttribute] | MTLVertexDescriptor | MTLVertexDescriptor(vertexAttributes:) | | MTLFunction | MTLVertexDescriptor? | .inferredVertexDescriptor() | | Swift struct | MTLVertexDescriptor | MTLVertexDescriptor(reflection: MyVertex.self) |

VertexDescriptor is a lightweight, Codable, Sendable value type with semantic annotations and normalization helpers — useful when you need to inspect, serialize, or manipulate vertex layouts before converting to the final MTLVertexDescriptor.
