# `some-mut`

A utility library that mainly lets you access a `Some` and then `take()` it infallibly.

Useful, for example, in a `Future` implementation, when you might re-enter into

a function multiple times and so can't `take()` until a sub-future is `Ready`:

```rust

// for a theoretical `StreamExt::forward()`/`SinkExt::send_all()` implementation:

fn poll(mut self: Pin<&mut Self>, cx: &mut Context<'_>) -> Poll> {

    if let Some(buffered_item) = self.buffered_item.some_mut() {

        ready!(self.sink.poll_ready(cx))?;

        self.sink.start_send(buffered_item.take())?;

    }

    // ...

}

```
