Struct Node

pub struct Node<'a> {
    pub position: u128,
    pub subitems: Vec<Vec<bool>>,
    /* private fields */
}

Fields

position: u128

The tranversal position.

subitems: Vec<Vec<bool>>

The node’s subitems in bits.

Implementations

impl Node<'_>

pub fn level(&self) -> u32

Get the level (depth) of the node.

pub fn parent(&mut self) -> Result<Node<'_>, NodeError>

Get the parent of the node.

pub fn child(&mut self, index: u8) -> Result<Node<'_>, NodeError>

Get a child of the node. Index 0 is the left child, index 1 is the right child.

pub fn is_leaf(&mut self) -> bool

Check if the node is a leaf (hasn’t got any children).

pub fn add_child( &mut self, index: u8, subitems: Vec<Vec<bool>>, overwrite: bool, ) -> Result<Node<'_>, NodeError>

Add a child to the node.

pub fn disable(&mut self) -> Result<(), NodeError>

Disables the node.

pub fn enable(&mut self) -> Result<(), NodeError>

Enables the node.

pub fn update(&mut self, subitems: Vec<Vec<bool>>) -> Result<(), NodeError>

Update the node’s subitems.

pub fn refresh(&mut self) -> Result<Node<'_>, NodeError>

Refresh the node’s data from the tree file.

Trait Implementations

impl<'a> Debug for Node<'a>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
