irontide-engine-support 1.0.2

Engine support primitives for irontide: crate-wide error/Result, I2P SAM client, transport abstraction, rate limiting, slot tuning, and the stats accumulator — the pure leaves shared by the engine runtime and session-core
Documentation

Engine support primitives for irontide.

This is the thin leaf crate that sits below both the engine runtime (irontide-engine) and irontide-session. It owns the pure, low-coupling mechanisms that both layers consume downward:

  • [error] — the crate-wide [Error]/[Result] type (#[from]-wraps the lower-crate errors plus [i2p::SamError]).
  • [i2p] — the I2P SAM-bridge client (co-located with error because Error #[from]-wraps i2p::SamError).
  • [transport] — the network transport abstraction (BoxedStream, NetworkFactory, TransportListener).
  • [rate_limiter] — the mixed-mode (GCRA) rate limiter.
  • [slot_tuner] — adaptive unchoke-slot tuning.
  • [stats] — the engine stats accumulator.

Extracted from irontide-session at M244b (the engine/session split). The grounding verified these six modules are pure leaves — the only intra-crate edge is error -> i2p (Error #[from] i2p::SamError), which is why the two co-locate here. Every other module has zero crate:: coupling.
