ReadOnly<U> 相同数组的别名，但重新解释为目标类型。
将数组重新解释为具有不同的数据类型（类型双关）。
The sizes of T and U must match. Reinterpret allows you to create a view into memory that has a different element size and length compared to the source array. For example, an array of float triples can be reinterpreted as an array of 3d vector structs.
