CONNECT-RUST SHIPS DEADLINE POLICY, BUFFA 0.6.0 LANDS WITH FEATURE GATES
By RepoJournal · Filed · About Anthropic
Connect-Rust closes three major ergonomic gaps in one release cycle: server-side timeout moderation, builder API consistency, and RequestContext stability for middleware.
The Connect-Rust team shipped three breaking changes that matter [1] [3] [5]. DeadlinePolicy [2] lets servers clamp untrusted client timeouts, preventing both denial-of-service (1ms cancellations, 24h hangs) and unbounded stream flows once handlers return. The Server builder now proxies all ConnectRpcService dispatch config through with_* methods [3] [4], eliminating the discovery tax of Server::from_service(...). RequestContext is now #[non_exhaustive] [5], locking the contract before post-0.4.0 ergonomics review adds service name, method name, RPC kind, and protocol negotiation fields that middleware needs. Buffa 0.6.0 is out [6] [7], finalizing feature-gated codegen and serde_json re-export, with buffa-build and protoc-gen-buffa now exposing gate_impls_on_crate_features for library crates [8] [9]. Claude-for-legal merged cleanup following CoCounsel integration [10] [11], normalizing whitespace, syncing metadata, and scrubbing stale skill names across thirteen plugin files. The plugins desk bumped box plugin SHA in claude-plugins-official [12].
