Constructs an event at the error 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::error;

let (err_info, port) = ("No connection", 22);

error!(port, error = %err_info);
error!(target: "app_events", "App Error: {}", err_info);
error!({ info = err_info }, "error on port: {}", port);
error!(name: "invalid_input", "Invalid input: {}", err_info);
