Constructs an event at the debug 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::debug;

let pos = Position { x: 3.234, y: -1.223 };

debug!(?pos.x, ?pos.y);
debug!(target: "app_events", position = ?pos, "New position");
debug!(name: "completed", position = ?pos);
