public

1	//! The integrations service: a workspace's connections to systems outside
2	//! g1t, and everything that crosses between them. See
3	//! `g1t_contracts::integrations` for what each connection does and the
4	//! methods and their arguments.
5	//!
6	//! Secrets are sealed at rest and never returned. A request an outside
7	//! system sends is checked against the connection's signing secret,
8	//! answered at once, and acted on afterwards, so a slow step never makes
9	//! the sender give up and send it again.
