Crate lrpc

Expand description

Use tcp to call functions synchronously between processes

§Examples

use lrpc::*;

#[derive(CommonStore, Debug)]
struct Point(i32, i32);

#[derive(CommonStore, Debug)]
struct Circle {
    center: Point,
    radius: u32,
}

#[fmt_function]
fn new_circle(p: Point, r: u32) -> Circle {
    Circle {
        center: p,
        radius: r,
    }
}

#[fmt_function]
fn circle_area(c: Circle) -> f64 {
    let f_radius = c.radius as f64;
    f_radius * f_radius * 3.14159
}

    srv_fun.regist("circle_area", circle_area);

    //start service
    std::thread::spawn(move || {
        service(srv_fun, "0.0.0.0:9009");
    });
    std::thread::sleep(std::time::Duration::from_millis(10));

    let mut conn = Connection::new("127.0.0.1:9009");
    let circle: Result<Circle> = conn.invoke(fun!("new_circle", Point(400, 300), 100));
