update Log Messages/Configure Logging sections #696
Description
there are instances of code that may have previously worked but are now outdated due to changes in the env_logger crate
use std::env;
use env_logger::Builder;
fn main() {
Builder::new()
.parse(&env::var("MY_APP_LOG").unwrap_or_default()) // Deprecated method
.init();
log::info!("informational message");
log::warn!("warning message");
log::error!("this is an error {}", "message");
