does rebinding an UnsafeMutablePointer<UnsafeMutablePointer<T>?> to a UnsafeMutablePointer<UnsafeMutablePointer<U>> also rebind the instance of T to U?
meaning, is the following code valid?
let buffer:UnsafeMutableBufferPointer<UnsafeMutablePointer<T>?> =
.init(start: start, count: count)
return try buffer.withMemoryRebound(to: UnsafeMutablePointer<U>.self)
{
...
}
or is it also necessary to rebind each sub-pointee individually? the sub-pointers came from a C API, and were all previously checked to be non-nil.

No, it does not recursively chase through pointers.
