How-To Guides

Task-oriented guides. Each page answers one question for someone who already knows the basics from the Tutorial .

• Pick the right primitive for the role-pair shape - map your concurrency shape (SPSC, MPSC, snapshot reads, etc.) to an MMF primitive.
• Async: cost and scaling - when to use sync / blocking / async on one handle, the measured per-op overhead, and the fixed-pool fan-out scaling.
• Write a custom Policy - implement the Policy trait so the sidecar swaps strategies on your own criteria.
• Compose primitives via SidecarBox - wrap any AdaptiveInstance so the sidecar manages it.
• Tune the observation ring + sidecar scan interval - knobs for the substrate and the control-plane scan loop.
• Bridge two hosts (QUIC / TCP / Sens-O-Matic) - connect rings across machines: certificates, the firewall step per OS, run commands, and the transport comparison.
• Tuning and overrides - every environment variable, Cargo feature, build recipe, and runtime probe in one place.
