Struct poldercast::Id

pub struct Id(_);

this is a poldercast unique identifier.

It can be used for different purposes:

• the unique identifier the a node identifies itself within the topology;
• a mean to compare 2 nodes within the topology

TODO: highlights which module is utilizing the Id for proximity (I think this is rings).

There is 2 ways to create a new Id:

1. you can [compute] from an address:

   let address: Address = "/ip4/127.0.0.1/tcp/8080".parse()?;
   let id = Id::compute(&address);

2. you can manually construct one;

   let id = Id::from(9283991);

Methods

impl Id

pub fn compute(address: &Address) -> Self
