Struct PeerId 

pub struct PeerId(pub Public);

Identity of a network peer.

This is just an Ed25519 public key. When forming a connection, each peer presents its identity in an X.509 certificate. The corresponding secret key is used to sign the connection handshake (the TLS protocol is used).

Note that the peer initiating a connection needn’t provide a certificate. In this case their identity is not known. For convenience, a tiny portion of the ID space is reserved for such anonymous peers. A mapping is provided between u64 and this space. It is assumed to be practically impossible to generate a secret key whose public key lies in this space.

Implementations

impl PeerId

pub fn anonymous(index: u64) -> Self

pub fn anonymous_index(&self) -> Option<u64>

Returns Some(index) if the peer ID is in the space reserved for anonymous peers.

pub fn to_text(&self) -> Text

Returns the text form of the peer ID.
