Implementations

impl Node

pub fn new( index: String, author: String, time_sent: u64, signatures: Vec<Signature>, contents: NodeContents, hash: Option<String>, ) -> Node

pub fn index_tail(&self) -> String

Extract the node’s final section (after the last /) of the index

pub fn parent_index(&self) -> Option<String>

Extract the Node’s parent’s index (if parent exists)

pub fn is_parent(&self, potential_child: &Node) -> bool

Check if a self is the direct parent of another Node.

pub fn is_ancestor(&self, potential_child: &Node) -> bool

Check if self is a parent (direct or indirect) of another Node

pub fn add_child(&self, new_child: &Node) -> Node

Creates a copy of self and searches through the children to find the deepest depth which the new_child can be placed.

pub fn time_sent_formatted(&self) -> String

Formats the time_sent field to be human readable date-time in UTC

pub fn to_json(&self) -> JsonValue

Converts to JsonValue creates a json object with one field: key = the node’s full index path, value = json representation of node

pub fn from_graph_update_json(wrapped_json: &JsonValue) -> Result<Node>

Convert from node JsonValue which is wrapped up in a few wrapper fields into a Node, with children if they exist.

pub fn from_json(json: &JsonValue) -> Result<Node>

Convert from straight node JsonValue to Node

Trait Implementations

impl Clone for Node

fn clone(&self) -> Node

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Node

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

Formats the value using the given formatter.
