Fort is proc macro attribute crate for Bastion.
[dependencies]
fort = "0.4"
bastion = "0.4"You can directly use fort to load work onto the root supervisor with:
#[fort::root]
async fn main(_: BastionContext) -> Result<(), ()> {
println!("Running in Bastion runtime!");
Ok(())
}Make your program fault-tolerant with fort:
#[fort::root]
async fn main(_: BastionContext) -> Result<(), ()> {
loop {
println!("Undying main!");
panic!("Error")
}
}You want to spawn multiple process
#[fort::root(redundancy = 10)]
async fn main(_: BastionContext) -> Result<(), ()> {
loop {
println!("Undying main!");
panic!("Error")
}
}use std::io::Write;
use std::net::TcpListener;
#[fort::root]
async fn main(_: BastionContext) -> Result<(), ()> {
let listener = TcpListener::bind("127.0.0.1:2278").unwrap();
println!("TCP server started at 127.0.0.1:2278");
for stream in listener.incoming() {
thread::spawn(|| {
let mut stream = stream.unwrap();
stream.write_all(b"Hello World\r\n").unwrap();
panic!("Fail in thread!");
});
panic!("Fail in event loop");
}
Ok(())
