some-mutA 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<Result<(), Error>> {
if let Some(buffered_item) = self.buffered_item.some_mut() {
ready!(self.sink.poll_ready(cx))?;
self.sink.start_send(buffered_item.take())?;
}
// ...
}
