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;
# // this is so the test will still work in no-std mode
# #[derive(Debug)]
# pub struct Ipv4Addr;
# impl Ipv4Addr { fn new(o1: u8, o2: u8, o3: u8, o4: u8) -> Self { Self } }
# fn main() {
# struct Connection { port: u32, speed: f32 }
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);
