kevy-client-async

Async client for kevy — a runtime-agnostic core with feature-gated transports for tokio, smol, and async-std. Mirrors the blocking kevy-client surface 1:1 so existing code paths can grep-replace Connection → AsyncConnection and add .await.

Status

Phase-4 first cut (kevy v3-cluster). Surface stabilizes when the v1.22.0 bundle ships — see the v3-cluster RFC for the locked Q4 design (mirror + pipeline-first).

Runtime selection

This crate has no default runtime. Exactly one of the following features must be enabled:

kevy-client-async = { version = "1", features = ["tokio"] }     # or "smol", or "async-std"

Enabling zero or more than one triggers a compile_error!.

Dep-rule exemption

This is the only kevy workspace crate allowed to take a third-party dep — the Rust async ecosystem has no std-only viable substrate. The exemption is documented inline in Cargo.toml and explained in the v3-cluster RFC (F5).
