ParallelScanFunc

[req.parallel_scan_func]

A type Scan satisfies ParallelScanFunc if it meets the following requirements:

ParallelScanFunc Requirements: Pseudo-Signature, Semantics

Value Scan::operator()(const Range &r, const Value &sum, bool is_final) const

Starting with sum, computes the summary and, for is_final == true, the scan result for range r. Returns the computed summary. Value type must be the same as a corresponding template parameter for the parallel_scan algorithm.
