3//! Various extention traits for providing asynchronous higher-order functions.
4//!
5//! # Examples
6//!
7//! ```
8//! # #[tokio::main]
9//! # async fn main() {
10//! // This won't make any name conflicts since all imports inside prelude are anonymous.
11//! use async_hofs::prelude::*;
12//!
13//! assert_eq!(
14//! Some(1).async_map(|x| async move { x + 2 }).await,
15//! Some(3),
16//! );
17//!
18//! type Result = core::result::Result<i32, i32>;
19//!
20//! assert_eq!(
21//! Result::Ok(1).async_and_then(|_| async move { Err(77) }).await,
22//! Result::Err(77)
23//! );
24//! # }
25//! ```
