Official Documentation

A Rust library providing macros to simplify the creation of asynchronous closures with external state captured by move. Useful for structuring asynchronous code with ease and clarity.

Installation

To install future-fn run cmd:

cargo add future-fn

Usage

use future_fn::*;
use std::time::Duration;
use tokio::time::sleep;

let string: String = String::from("test");
let number: i32 = 1;
let future_fn = future_fn!(string, number, {
    let tmp_string: String = String::from("test");
    assert_eq!(string, tmp_string);
    assert_eq!(number, 1);
});
future_fn().await;

let future_fn = future_fn!(string, number, |data| {
    let tmp_string: String = String::from("test");
    sleep(Duration::from_millis(360)).await;
    assert_eq!(string, tmp_string);
    assert_eq!(data, 1);
    assert_eq!(number, 1);
});
future_fn(1).await;

let future_fn = future_fn!(string, number, |data: i32| {
    let tmp_string: String = String::from("test");
    sleep(Duration::from_millis(360)).await;
    assert_eq!(string, tmp_string);
    assert_eq!(data, 1);
    assert_eq!(number, 1);
    sleep(Duration::from_millis(360)).await;
});
future_fn(1).await;

let future_fn = future_fn!(string, number, |data: i32| {
    let tmp_string: String = String::from("test");
    sleep(Duration::from_millis(360)).await;
    assert_eq!(string, tmp_string);
    assert_eq!(data, 1);
    assert_eq!(number, 1);
});
future_fn(1).await;
