Struct Oracle 

pub struct Oracle<C: PublicKey> { /* private fields */ }

Mechanism to register authorized peers.

Peers that are not explicitly authorized will be blocked by commonware-p2p.

Trait Implementations

impl<C: PublicKey> Blocker for Oracle<C>

type PublicKey = C

Public key type used to identify peers.

async fn block(&mut self, public_key: Self::PublicKey)

Block a peer, disconnecting them if currently connected and preventing future connections.

impl<C: Clone + PublicKey> Clone for Oracle<C>

fn clone(&self) -> Oracle<C>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<C: Debug + PublicKey> Debug for Oracle<C>

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

Formats the value using the given formatter.

impl<C: PublicKey> Manager for Oracle<C>

async fn update(&mut self, index: u64, peers: Self::Peers)

Register a set of authorized peers at a given index.

These peer sets are used to construct a bit vector (sorted by public key) to share knowledge about dialable IPs. If a peer does not yet have an index associated with a bit vector, the discovery message will be dropped.

Parameters

• index - Index of the set of authorized peers (like a blockchain height). Must be monotonically increasing, per the rules of Ordered.
• peers - Vector of authorized peers at an index (does not need to be sorted).

type PublicKey = C

Public key type used to identify peers.

type Peers = Ordered<C>

The type for the peer set in registration.

async fn peer_set(&mut self, id: u64) -> Option<Ordered<Self::PublicKey>>

Fetch the ordered set of peers for a given ID.

async fn subscribe( &mut self, ) -> UnboundedReceiver<(u64, Ordered<Self::PublicKey>, Ordered<Self::PublicKey>)>

Subscribe to notifications when new peer sets are added.
