//! use bstr::ByteSlice;

//! let auto_crlf: bool = Boolean::try_from("true".as_bytes().as_bstr()).unwrap().into();

//!
//! let packed_limit = Integer::try_from("10m".as_bytes().as_bstr()).unwrap();
//! assert_eq!(packed_limit.to_decimal(), Some(10 * 1024 * 1024));
//!
//! let ignore_revs = Path::from(Cow::Borrowed(b":(optional)~/.git-blame-ignore-revs".as_bstr()));
//! assert!(ignore_revs.is_optional);
