Module connection 

A QUIC connection kept warm across many requests on one ALPN ([connection::WarmConnection]): one dial amortized over every request, one bi-stream per request (no wire change), closed once on the handle’s own Drop; and the map of one such connection per node on one ALPN (connection::Connections), shared by a CLI command or by a node’s outbound pull legs and DHT calls. Dialling connections, and connections kept warm across many requests.

dial is the one dial every requester path uses, one-shot or warm. It runs the dial on a caller-chosen runtime when the caller asks for one, so the connection’s QUIC driver lives there.

[WarmConnection] dials once and stays open, so a caller fetching many hashes from one provider pays the dial + NAT-traversal cost a single time and opens a fresh bi-stream per hash instead. The wire is unchanged — one stream still carries exactly one hash (open_progressive_pull_on opens the bi-stream); only the client-side teardown differs, because a per-hash pull leaves the connection open for the next one rather than closing it.

Connections keeps one [WarmConnection] per node on one ALPN, so every caller sharing the map (every lane and entry of a CLI command, or every outbound pull leg or DHT call of a node) dials each node once.

Connections

One live connection per node on one ALPN, shared by every pull of one command (cdn/client/v1, from new) or by every outbound call of one node (with_options).
