Function json 

pub fn json()

Turns on the json defaults which is one line of flattened json per event with RFC3339 UTC time, activating it globally on all threads.

Panics

Will panic if a global default is already set

Examples

traceon::json();
traceon::info!("a json message");

output prettified:

{
  "time": "2023-01-02T04:46:12.715798+00:00",
  "level": "INFO",
  "message": "a json message"
}
