Struct sc_network::PeerId [−][src]
pub struct PeerId { /* fields omitted */ }
Expand description
Identifier of a peer of the network.
The data is a multihash of the public key of the peer.
Implementations
Builds a PeerId
from a public key.
Tries to turn a Multihash
into a PeerId
.
If the multihash does not use a valid hashing algorithm for peer IDs,
or the hash value does not satisfy the constraints for a hashed
peer ID, it is returned as an Err
.
Generates a random peer ID from a cryptographically secure PRNG.
This is useful for randomly walking on a DHT, or for testing purposes.
Checks whether the public key passed as parameter matches the public key of this PeerId
.
Returns None
if this PeerId
s hash algorithm is not supported when encoding the
given public key, otherwise Some
boolean as the result of an equality check.
