Forwards all allocations/deallocations to the PoolResource.
Main entry point to nanobench's benchmarking facility.
Bench & run(char const *benchmarkName, Op &&op)
Repeatedly calls op() based on the configuration, and performs measurements.
ANKERL_NANOBENCH(NODISCARD) std Bench & batch(T b) noexcept
Sets the batch size.
ANKERL_NANOBENCH(NODISCARD) std Bench & minEpochIterations(uint64_t numIters) noexcept
Sets the minimum number of iterations each epoch should take.
An extremely fast random generator.
