Adapt an arbitrary accept/connect transport (i.e. TCP) to be a Link provider - #5
Merged
Conversation
The design of record for rumors::link::routed: one connection per stream behind a per-process router, a token-routed connect header with a one-RTT establishment acknowledgement, generic over a caller-supplied Dial/Listen seam (opaque addresses, no IP binding). Records the decisions: in-crate module, per-link token, single-use connections, caller-driven router with count-bounded header reads, pooling deferred to the Dial seam (with the qorb evaluation), no discovery in v1.
rumors::link::routed adapts any accept/connect byte-stream transport (a caller-supplied Dial/Listen pair; addresses are opaque names in the caller's namespace, not IP) into a Link: one connection per stream, routed to its link by a token-bearing connect header, with a one-RTT establishment acknowledgement making token registration on both routers happen-before either end's first stream open. The router is a caller-driven future (the crate still spawns nothing and needs no runtime or clock): per-connection header reads run as concurrent futures bounded by count with oldest-first eviction, delivery into per-link queues is try_send-only, and a queue overflow evicts the whole link so misbehavior surfaces as transport failure instead of a silently lost stream. Dropping a link revokes its routing at that moment. Validated by the exported conformance suite over TCP (default and OS-floor buffers, both construction orientations) and over a string- named in-memory network, plus a three-endpoint mesh converging by concurrent gossip beside a connection stalled mid-header, and unit suites for the wire format and every router-discipline clause.
…aths Rename Token::mint() to Token::new(), and import the handful of names the new modules had been spelling out inline (Entry, HashMap, MutexGuard, TrySendError, IpAddr, fmt, split, duplex, select, try_join, Link, LinkInfo).
