Struct duniter_wotb::WebOfTrust

pub struct WebOfTrust {
    pub max_cert: usize,
    // some fields omitted
}

Store a Web of Trust.

Allow to create/remove nodes and links between them.

It provides methods to find sentries nodes, find all paths between 2 nodes and to compute distances in the web.

Fields

max_cert: usize

Maxiumum amout of certifications a node can provide.

It can be changed afterward, and will be accounted for every future calculations.

In practice it should not change after initialization.

Methods

impl WebOfTrust

fn new(max_cert: usize) -> WebOfTrust

Create a new Web of Trust with the maxium certificications count.

fn from_file(path: &str) -> Option<WebOfTrust>

fn to_file(&self, path: &str) -> bool

Write WoT to file.

fn add_node(&mut self) -> NodeId

Add a new node.

fn remove_node(&mut self) -> Option<NodeId>

Remove given node if it exits.

fn compute_distance(
    &self,
    member: NodeId,
    d_min: u32,
    k_max: u32,
    x_percent: f64
) -> WotDistance

fn is_outdistanced(
    &self,
    node: NodeId,
    d_min: u32,
    d_max: u32,
    x_percent: f64
) -> Option<bool>

Test if a node is outdistanced in the network.
