Macro woodpecker::wp_init

macro_rules! wp_init {
    () => { ... };
    ($config:expr) => { ... };
}

Initializes the crate's kitchen.

An optional parameter may be passed to define initial logging configuration.

Takes into account RUST_LOG environment variable which must conform to the spec.

The WP_LOG_THREAD environment variable overrides the passed configuration.

Example

#[macro_use]
extern crate woodpecker;
use woodpecker as wp;

fn main() {
    wp_init!();

    wp_set_level!(wp::LogLevel::INFO).unwrap();
    info!("Coucou!");
}

If log thread is activated consider using sync to ensure that all log records are properly flushed.

Example

#[macro_use]
extern crate woodpecker;
use woodpecker as wp;

use std::sync::{Arc, Mutex};
use std::ops::Deref;

fn main() {
    wp_init!(wp::Config { thread: true, ..Default::default() });

    let out = Arc::new(Mutex::new(String::new()));
    {
        let out = out.clone();
        wp_register_handler!(Box::new(move |record| {
            out.lock().unwrap().push_str(record.msg().deref());
        }));

        warn!("foo");
    }

    wp::sync();

    assert_eq!(*out.lock().unwrap(), "foo".to_string());
}
