The BidiStreamSource trait (ADR-070) made Connection hold Box<dyn BidiStreamSource> so downstream crates can add connection shapes without editing core — but the public constructor for that path was missing. The source field is private; the channels crate (or any future crate) had no way to build a Connection from its own BidiStreamSource impl. The trait was unusable from outside core. Add Connection::from_source(source: impl BidiStreamSource, alpn: Vec<u8>) -> Self: the extension point. Takes impl BidiStreamSource (not Box<dyn>) to match the ergonomic style of from_stream / from_bidi; boxes the source internally. No feature gate (always available, like from_stream). Initializes alpn and identity: OnceLock::new() the same as the other constructors. Test: a custom RecordingSource BidiStreamSource impl (not a built-in) constructed via from_source, verifying remote_alpn / remote_addr / accept_bi (round-trips real bytes via tokio::io::duplex) / open_bi (StreamClosed) / close (records code+reason) all delegate to the custom impl. Verified: cargo test + clippy clean across default, --no-default-features, --features iroh, --all-features; cargo check -p alknet-call succeeds unchanged; cargo fmt --check passes.
Alknet
Status: Pre-alpha — This project is undergoing a major architectural pivot to an ALPN-as-service model. The previous implementation has been archived and a greenfield rebuild is in progress.
A self-hostable networking toolkit built on QUIC+TLS with ALPN-based protocol dispatch. Each protocol handler (SSH, SFTP, Git, HTTP, DNS, messaging, call protocol) registers an ALPN string on a shared endpoint. The ALPN negotiation during the TLS/QUIC handshake routes connections to the correct handler before any application bytes are read.
Core Insight
A service IS an ALPN. One endpoint, one port, many protocols — dispatched by the TLS handshake, not by application-level peeking or separate listeners.
