Services

Create service instance (Singleton) in one step

use wildbird::derive::*;

// Convert struct to Service + impl construct()

#[service(construct = "init")]
struct HelloService {
    component_name: String,
}

impl HelloService {
    fn init() -> HelloService {
        HelloService {
            component_name: "Hello penguins 🐧".to_string(),
        }
    }

    fn sey_hello(&self) {
        println!("Hello! 👋")
    }
}

fn main() {
    HelloService.sey_hello();
}

• Async init

use wildbird::derive::*;

#[service(construct = "async init")]
struct AsyncService {}

impl AsyncService {
    async fn init() -> AsyncService {
        AsyncService {}
    }

    fn greeting(&self) {
        println!("Hello 🗼")
    }
}

fn main() {
    AsyncService.greeting();
}

• Async init functional

use wildbird::derive::*;

// Convert struct to Service
#[service]
struct HelloService {
    component_name: String,
}

// Impl Service trait construct() 
#[service(construct)]
async fn hello_init() -> HelloService {
    HelloService {
        component_name: "Hello 🚀".to_string(),
    }
}

Globals

Create global

use wildbird::derive::*;

#[var]
pub fn my_name() -> String {
    String::from("Hawk 🦅")
}

fn main() {
    println!("Hello from 🇵🇱, {}", MY_NAME);
}

• Custom name

use wildbird::derive::*;

#[var(name = "HOME")]
fn custom_name() -> String {
    std::env::var("HOME").expect("env:HOME not found")
}

fn main() {
    println!("Home: {}", HOME);
}

• Async init

use std::time::Duration;
use wildbird::derive::*;
use std::thread::sleep;

#[var(name = "USERS")]
async fn http_fetch_users() -> String {
    sleep(Duration::from_millis(200));
    String::from("⏱️")
}

fn main() {
    println!("Users: {}", USERS);
}
