Wanted

It would be great to have the following features added to Divan. If you have ideas to expand this list, please find or create a discussion first.

• Async benchmarks

• Baseline benchmark

  • Should match baselines across equal generic types and constants
  • Idea:

  #[divan::bench]
  fn old() { ... }
  
  #[divan::bench(baseline = old)]
  fn new() { ... }

• Cross-device: run benchmarks on other devices and report the data on the local device

• HTML output

• CSV output

• Custom counters

• Time complexity of counters

  • Also space complexity when measuring heap allocation

• Measure heap allocations

  • Custom GlobalAlloc that wraps another GlobalAlloc, defaulting to System

• Custom timers

• Timer for kernel/user mode

  • Unix:
    • getrusage(2)
    • Per-thread:
      • Linux/FreeBSD/OpenBSD: RUSAGE_THREAD
      • macOS/iOS: thread_info(mach_thread_self(), ...)
  • Windows:
    • GetProcessTimes
    • GetThreadTimes
