PeerDb

ts_runtime::peer_tracker

Struct PeerDb 

Source 
pub struct PeerDb { /* private fields */ }
Expand description

A database that stores a map of peers by PeerId and multiple indices.

Assumes that all indexed fields are unique per-node, with a few notable exceptions:

  • Hostname may be duplicated, though the fqdn (including the tailnet component) may not be.
  • Accepted routes may overlap.

Implementations§

Source§

impl PeerDb

Source

pub fn upsert(&mut self, new: &Node) -> PeerId

Upsert a node into the peer db.

The StableNodeId is used as the primary key to identify the node.

Source

pub fn remove(&mut self, field: &dyn IndexedField) -> Option<(PeerId, Node)>

Remove a peer by a given indexed field.

Source

pub fn get(&self, field: &dyn IndexedField) -> Option<(PeerId, &Node)>

Get the node with the given field.

Source

pub fn get_route(&self, route: IpNet) -> impl Iterator<Item = (PeerId, &Node)>

Get the nodes with the closest matching route.

Source

pub fn has(&self, field: &dyn IndexedField) -> Option<PeerId>

Check whether there is a peer with the given field in the db.

Source

pub const fn peers(&self) -> &HashMap<PeerId, Node>

Get a reference to the peer map.

Source

pub fn retain(&mut self, predicate: impl FnMut(PeerId, &Node) -> bool)

Remove the nodes in the db that don’t satisfy the predicate function.
