//!Provides you with global tokio runtimes
//!
//!It can be used from any point in code without need to manually pass around runtime itself
//!Or being forced to use tokio macros
//!
//!## Example
//!
//!```rust
//!use tokio_global::{Runtime, AutoRuntime};
//!use tokio::io::{AsyncWriteExt, AsyncReadExt};
//!
//!async fn server() {
//!    let mut listener = tokio::net::TcpListener::bind("127.0.0.1:8080").await.expect("To bind");
//!
//!    let (mut socket, _) = listener.accept().await.expect("To accept connection");
//!
//!    async move {
//!        let mut buf = [0; 1024];
//!        loop {
//!            match socket.read(&mut buf).await {
//!                // socket closed
//!                Ok(0) => return,
//!                Ok(_) => continue,
//!                Err(_) => panic!("Error :("),
//!            };
//!        }
//!    }.spawn().await.expect("Finish listening");
//!}
//!
//!async fn client() {
//!    let mut stream = tokio::net::TcpStream::connect("127.0.0.1:8080").await.expect("Connect");
//!
//!    // Write some data.
//!    stream.write_all(b"hello world!").await.expect("Write");
//!
//!    //Stop runtime
//!    Runtime::stop();
//!}
//!
//!let _guard = Runtime::default();
//!
//!let runner = std::thread::spawn(|| {
//!    Runtime::run();
//!});
//!
//!server().spawn();
//!client().spawn();
