settimeout/
lib.rs

1//! Contains some utility features to create a [`Future`](/std/future/trait.Future.html) implementation
2//! to be used in any async function.
3//!
4//! # Examples
5//!
6//! Create a [`Future`](/std/future/trait.Future.html) to be ready after some point:
7//!
8//! ```
9//! use std::time::Duration;
10//! use settimeout::set_timeout;
11//! use futures::executor::block_on;
12//!
13//! async fn foo() {
14//!   println!("The Future will be ready after some time");
15//!   set_timeout(Duration::from_secs(5)).await;
16//!   println!("Now, it is ready");
17//! }
18//!
19//! block_on(foo());
20//! ```
