# `async-stream-lite`
It's [`async-stream`](https://lib.rs/crates/async-stream), but without proc macros.
```rs
use async_stream_lite::async_stream;
use futures_util::{pin_mut, stream::StreamExt};
#[tokio::main]
async fn main() {
let stream = async_stream(|yielder| async move {
for i in 0..3 {
yielder.y(i).await;
}
});
pin_mut!(stream);
while let Some(value) = stream.next().await {
println!("got {}", value);
}
}
```
## `#![no_std]` support
`async-stream-lite` supports `#![no_std]`, but requires `alloc`.
