- crud is now the demonstrator: app owns smarm runtime + root supervisor,
store actor and urus::endpoint as ordered siblings (store first, so
reverse-order shutdown drains HTTP before stopping the store),
Shutdown::Infinity on the endpoint, shutdown via
rt.handle().request_shutdown(root_sup) from the stdin thread.
Deletes two kludges the old shape forced:
* static OnceLock<Sender> spawn-on-first-use -> a supervised child
that self-registers a typed Name; handlers use smarm::send per
request and turn 'between incarnations' into a 503 instead of
panicking on a dropped store.
* static SHUTTING_DOWN AtomicBool + 250ms recv_timeout poll in the
store loop and in the SSE ticker -> a plain park; the tree stops
both. Smoke-tested live: CRUD round-trips, SSE stream, clean drain
with the stream open, port closed after.
- Other examples stay short and on serve*, updated for the split config
(serve_with(cfg, smarm::Config, pipe) / serve_with_shutdown(..., signal)).
plain_serve's URUS_SCHED_THREADS now builds a smarm::Config.
ws_chat's doc block explains the OnceLock is a serve*-only workaround
and points at crud for the clean shape.
- README: new 'Your Own Supervision Tree' section (endpoint as the real
API), graceful shutdown reframed as the serve*-only path, Config table
loses scheduler_threads and gains name, PubSub rule 1 notes the
supervised-sibling alternative.
111 lib + 50 integration + 2 doc tests green; clippy clean.
examples/channels_chat.rs (required-features phoenix): ephemeral
room:* and persistent session:* side by side over phoenix.js V2 JSON,
stdin-driven graceful shutdown (the ws_chat pattern). Smoke-tested
live: rejoin after transport drop lands on the same instance (state
counter persists across three transports), broadcasts carry the new
join generation's ref.
README: channels section (feature split, core trait walkthrough,
session persistence semantics incl. the re-entrant-join contract).
ROADMAP: v0.6 marked done with the full as-landed decision list,
chunked as committed.
