Branch an asynchronous stream into two, pushing all items to both halves.
The resulting branches will can be polled independently from each other and will
receive all items from the underlying stream (which must be Clone).
As long as both halves are alive, one half will never outpace the other by more than a fixed number of items.
This library is runtime agnostic. It is verified to work on both async_std
and tokio.
```rust use futures::{stream, prelude::*};
let (mut left, mut right) = gabelung::new(stream::repeat(1u8));
asserteq!(left.next().await, Some(1u8)); asserteq!(right.next().await, Some(1u8)); ```
