Same reasoning as `async_channel` — the problem is simpler than what `flume` solves. | +| `futures::channel::oneshot` | Adds the `futures` crate as a dependency.

It is intended for broad adoption across the Rust ecosystem, including +use in projects under a variety of open-source and proprietary licenses. + +The two most common choices for Rust crates are MIT and Apache-2.0 (often +dual-licensed as `MIT OR Apache-2.0`). A license decision is needed. + +## Decision + +Use the **MIT license** exclusively (not dual-licensed with Apache-2.0). + +## Rationale + +- **Maximum compatibility**: MIT is compatible with a strictly wider range of + downstream projects than Apache-2.0.
