c# - 是否存在稀疏 Span对于多个内存部分？

Question

考虑：

        public struct Foo
        {
            public float value;
        }

        static void Main(string[] args)
        {
            var array = new Foo[10];

            var block1 = new Memory<Foo>(array, 0, 3);
            var block2 = new Memory<Foo>(array, 4, 6);

            var span1 = block1.Span;
            var span2 = block2.Span;

            foreach (ref var  f in span1) { /* do work */ }
            foreach (ref var  f in span2) { /* do work */ }

            var blocks = new[] { block1, block2 };

            foreach (var block in blocks)
            {
                foreach (ref var f in block.Span)
                {
                    /* do work */
                }
            }

            // preferred would be:
            foreach (ref var f in new Span<Foo>(blocks))
            {
                /* do work */
            }
        }

是否有一个跨度结构可以让您覆盖多个内存块？我可以编写一个自定义枚举器，但是为每个元素调用 Memory.Span 很慢。
