/// This type can be used to generate kana mnemonics from any data.
/// It wraps a type implementing `std::io::Read` and produces a kana mnemonic reading from the stream until its end.

/// # use khash::Digest;
/// let input = "Hello world!";
/// let mnemonic: String = Digest::new(&mut input.as_bytes()).collect(); // Read the bytes from the `input` string and collect the kana mnemonic into a `String`
