Cargo Features

IteratorItem has no features set by default.

[dependencies]
iterator_item = { version = "0.2.0", features = ["std_async_iter"] }
std_async_iter

For now this isn't yet useful, as Stream is in flux (its API changed and being renamed to AsyncIterator), but can be used in the future (or with a little bit of duplicated output in the async fn* desugaring): https://rust-lang.github.io/wg-async-foundations/vision/roadmap/async_iter/traits.html
