Specify which struct method and property requires write access to be invoked.
Used in conjunction with the ReadOnlyAttribute, WriteAccessRequiredAttribute lets you specify which struct method and property
requires write access to be invoked. When you add the ReadOnly attribute to a native container, it indicates that only operations that read data can be
performed on the native container, and you can't use methods and properties on the native container that modify the array. The WriteAccessRequired
attribute
indicates which methods and properties can't be used on a native container with the ReadOnly attribute.
