I’m getting this error:

> What is the name of this patch? thread ‘main’ panicked at ‘called `Result::unwrap()` on an `Err` value: Custom { kind: UnexpectedEof, error: StringError(“failed to fill whole buffer”) }’, src/libcore/result.rs:997:5  
> note: Run with `RUST_BACKTRACE=1` environment variable to display a backtrace.

I don’t know if it’s a coincidence or not that this is my very longest patch I’ve done thus far and the first time seeing this error.
