Function generate_stream 

pub fn generate_stream<T: Read + ?Sized>(
    context: &Context,
    from: &mut T,
) -> Result<(usize, String), Error>

Generate kana hash from a stream of bytes with this digest.

Example

To generate a hash from a file with the default digest

fn hash_file(file_name: impl AsRef<Path>) -> String
{
    let mut file = OpenOptions::new()
	.read(true)
	.open(file_name).expect("Failed to open file");
 
    let file_size = file.metadata().expect("Failed to stat file").len();
 
    let (bytes_read, hash) = generate_stream(&Default::default(), &mut file).expect("Failed to generate hash from file");
    assert_eq!(bytes_read as u64, file_size, "Failed to read whole file");
 
    hash
}
