(I'm just starting off with rust, so please be patient)

Is there an idiomatic way of writing the following as a one-liner, somehow informing rustc that it should keep the PathBuf around?

```rust // nevermind the fully-qualified names // they are there to clarify the code // (that's what I hope at least)

let dir: std::path::PathBuf = std::env::current_dir().unwrap(); let dir: &std::path::Path = dir.as_path();

// this won't do: // let dir = std::env::current_dir().unwrap().as_path(); ``` I do understand why rust complains that "temporary value dropped while borrowed" (I mean, the message says it all), but, since I don't really need the PathBuf for anything else, I was wondering if there's an idiomatic to tell rust that it should extend its life until the end of the code block.
