Class thrust::device_vector

A device_vector is a container that supports random access to elements, constant time removal of elements at the end, and linear time insertion and removal of elements at the beginning or in the middle. The number of elements in a device_vector may vary dynamically; memory management is automatic. The memory associated with a device_vector resides in the memory accessible to devices.
