Generic Instance Method


Call body(p), where p is a pointer to the collection’s contiguous storage. If no such storage exists, it is first created. If the collection does not support an internal representation in a form of contiguous storage, body is not called and nil is returned.


func withContiguousStorageIfAvailable<R>(_ body: (UnsafeBufferPointer<Bound>) throws -> R) rethrows -> R?
Available when Bound conforms to Strideable and Bound.Stride conforms to SignedInteger.


A Collection that provides its own implementation of this method must also guarantee that an equivalent buffer of its SubSequence can be generated by advancing the pointer by the distance to the slice’s startIndex.
