Class thrust::host_vector

A host_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 host_vector may vary dynamically; memory management is automatic. The memory associated with a host_vector resides in memory accessible to hosts.
