Struct duniter_wotb::data::legacy::LegacyWebOfTrust

pub struct LegacyWebOfTrust {
    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 LegacyWebOfTrust

pub fn legacy_from_file(path: &str) -> Option<LegacyWebOfTrust>

Read WoT from file.

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

Write WoT to file.

fn get_sentries(&self, sentry_requirement: usize) -> Vec<NodeId>

Get sentries array.

fn get_non_sentries(&self, sentry_requirement: usize) -> Vec<NodeId>

Get non sentries array.

fn get_links_source(&self, target: NodeId) -> Option<Vec<NodeId>>
