# Completion-based async runtime. We use the umbrella `compio = "0.18"`
# crate so all sub crates pull as a unit (matches iggy's setup, lets us
# share `cyper-axum`'s expected version line). The historic concern in
# this codebase was the umbrella `compio = "0.6"` kqueue driver having
# open-fd attachment bugs; that was twelve releases ago, and the 0.18
# series ships the same `compio-runtime 0.11` / `compio-fs 0.11` /
# `compio-io 0.9` / `compio-buf 0.8` / `compio-driver 0.11` /
# `compio-macros 0.1.2` we were pinning manually, so the API surface we
# depend on is byte-identical. The only sub-crate that moves is
# `compio-tls` from our direct 0.9 pin to 0.4 (pulled transitively via
# the umbrella). API surface (`TlsAcceptor`, `TlsConnector`,
# `TlsStream`) is the same.
#
# Features mirror iggy except we omit `quic` and `ws` (not used).
# `aws_lc_rs` is selected for rustls's crypto provider via our direct
# `rustls` dep below; compio's `rustls` feature only enables the
# `compio-tls/rustls` adapter without forcing a backend.

# HTTP wire layer + routing. Cyper bridges hyper's `hyper::rt::Read`/
# `hyper::rt::Write` traits to compio's I/O surface so we get hyper's
# full HTTP/1.1 implementation running on our compio runtime + io_uring.
# Cyper-axum is the matching axum::serve replacement (axum runs on top
# of any tower::Service-driven hyper).
#
# Tokio gets linked transitively (via hyper, hyper-util, h2, axum) but
# is dormant: cyper supplies its own `CompioExecutor` + `CompioTimer`
# adapters, so hyper never starts a tokio runtime, never spawns tokio
# threads, never calls `tokio::time::sleep`. Verified: only
# `tokio::sync::watch` runs (used by hyper-util for graceful shutdown
# signalling — pure userspace channel, no runtime needed). Iggy ships
# this configuration in production.
#
# `send_wrapper` lets us use compio's `!Send` futures inside tower's
# Send-bound `Service::Future` slot. Each runtime is single-threaded
# so the SendWrapper's panic-on-cross-thread guard never fires.
#
# Inter-node RPC plane is HTTP/2 over mTLS: every node is both a cyper
# client (`RemoteBackend`) and a cyper-axum server (`rpc_server`). Both
# halves require the `http2` feature, which switches `hyper-util`'s
# legacy::Client and `hyper_util::server::conn::auto::Builder` from h1-
# only to ALPN-driven h1+h2. ALPN selects h2 because rustls is configured
# with `alpn_protocols = vec![b"h2"]` on both ServerConfig and
# ClientConfig in `tls_material.rs`. The `stream` feature surfaces
# `Response::bytes_stream()` for streaming GETs and `Body::stream(...)`
# for streaming PUTs — used by `remote_fs::RemoteRead/WriteSink`. The
# old custom binary protocol over raw TCP (length-prefixed bincode
# envelopes + per-call `dial()`) is gone with this commit; `cyper`
# replaces every byte of that wire path.
