Macro async_for

async_for!() { /* proc-macro */ }

This macro can let you use async Stream with for loop like Iterator.

Example

 use async_for::async_for;
 use futures_util::{stream, StreamExt};

 futures_executor::block_on(async {
     let mut result = vec![];

  async_for! {
      async for n in stream::iter(vec![1, 2, 3]) {
          result.push(n);
      }
  }

  assert_eq!(result, vec![1, 2, 3]);
 })
