pub const BACKEND_INACTIVITY_TIMEOUT: Duration;Available on crate feature
zbus-backend only.Expand description
The inactivity window after which a CPDB backend process auto-exits.
Backends terminate themselves after this long with no D-Bus activity.
Users of CpdbClient::discovery_stream don’t need to think about
this — the returned stream spawns a keep-alive task that pings at
BACKEND_INACTIVITY_TIMEOUT / 3. Exposed for callers that drive
their own keep-alive loops (see the discover_printers example).
