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,
);
info!(name: "completed", "completed connection to {:?}", addr);
