Function init

pub async fn init(
    log_file: Option<&str>,
    level: Option<LevelFilter>,
    extra_levels: Option<HashMap<&str, LevelFilter>>,
) -> Result<(InitContext, Receiver<i32>)>

The main function. Call it as soon as possible in your program. It returns the context and the channel to listen the exit requests

use wixet_bootstrap::init;
use log::info;
 
#[tokio::main]
async fn main() {
    info!("This log line will be ignored because the logger is not configured yet");
    let (closer, exit) = init(Some("output.log")).await?; //If you provide None, it simple will not write a log file (just output)
    info!("Hello to my application!")
 
    // Do may awesome stuff spawing tokio tasks
 
    // I use select here because it is common to listen for multiple signals, but you can just await the `exit` if not
    tokio::select!{
        _ = exit.recv_async() => {
        info!("Shutdown process started");
        // Do your friendly stop process here
        // This code is run when ctrl+c or any other kill interrupt is received
    }
};
 
// A friendly shutdown by deinitializing all "init" stuff.
closer.stop().await?;
info!("Bye");
