class copy_instruction

Declaration

class copy_instruction : public implement_acceptor { /* full declaration omitted */ };

Description

Copies one or more subranges of elements from one allocation to another, potentially between different memories. Source and destination can be box-shaped allocations (in which case we consider the copy region boxes to be contained within the allocation box) or linearized (such that boxes are laid out sequentially in memory, which must have space for copy_region.get_area() elements).
