Methods
impl<T: PartialOrd + KnownSize + Debug> Bnode<T>
fn create(node_list: SortedList<KeyAddr<T>>, father: u64, leftbrother: Option<u64>, rightbrother: Option<u64>, is_leaf: bool, is_root: bool, order: u64) -> Bnode<T>
creates a new Bnode Object all u64 fields are addresses to other nodes
fn read(file: &mut File, addr: Option<u64>) -> Result<Bnode<T>>
reads a Bnode from disc at the specefied addr in the specified file
fn write(&mut self, file: &mut File, addr: Option<u64>) -> Result<()>
writes a Bnode from disc at the specefied addr in the specified file
fn size(order: u64) -> u64
returns the size of the Bnode calculated using the order of the hosting B* tree
