Expand description
Constructs an event at the info level.
This functions similarly to the event!
macro. See the top-level
documentation for details on the syntax accepted by
this macro.
§Examples
use tracing::info;
use tracing::field;
let addr = Ipv4Addr::new(127, 0, 0, 1);
let conn = Connection { port: 40, speed: 3.20 };
info!(conn.port, "connected to {:?}", addr);
info!(
target: "connection_events",
ip = ?addr,
conn.port,
?conn.speed,
);
