@peerbit/network-rust

Native (wasm-bindgen) wire codec and batched signature verification for the Peerbit direct-stream envelope (peerbit_wire crate).

The crate decodes the borsh envelope from @peerbit/stream-interface (DataMessage/ACK/Hello/Goodbye, all delivery modes, multi-signature headers) byte-identically, applies the signable-bytes rule (delivery mode and signatures are excluded from the signed range) and batch-verifies sha256-prehashed Ed25519 signatures with ed25519-dalek.

createNativeWire() returns a module whose decodeAndVerifyBatch plugs into the nativeWire option of @peerbit/stream's DirectStream (default off; the TS path is unchanged when disabled).

The crate also contains the native protocol cores (direct-stream state machine, topic control plane, fanout tree, block exchange); createRustCoreStream() implements the rustCore option of the DirectStream family. See ARCHITECTURE.md for the as-built architecture of the whole native network plane, including the receive fusion hosted by @peerbit/native-backbone and the peerbit/rust client preset.

Golden-vector parity tests against the TS implementation live in test/. The codec-parity subset (wire, topic-control, fanout) also runs under headless Chromium via npm run test:browser; the session-based specs are node-only (they need TCP). A browser end-to-end smoke of rust-core mode lives in packages/transport/stream/e2e/browser (npm run test:rust-core there).
