Function newline_converter::dos2unix

pub fn dos2unix<T: AsRef<str> + ?Sized>(input: &T) -> Cow<'_, str>

Converts DOS-style line endings (\r\n) to UNIX-style (\n).

The input string may already be in correct format, so this function returns Cow<str>, to avoid unnecessary allocation and copying.

Examples

assert_eq!(newline_converter::dos2unix("\r\nfoo\r\nbar\r\n"), "\nfoo\nbar\n");

Lone \r bytes will be preserved:

 assert_eq!(
   newline_converter::dos2unix("\nfoo\rbar\r\n"),
   "\nfoo\rbar\n"
 );
