Struct NetworkInfo 

Source 
pub struct NetworkInfo<N> { /* private fields */ }
Expand description

Common data shared between algorithms: the nodes’ IDs and key shares.

Implementations§

Source§

impl<N: NodeIdT> NetworkInfo<N>

Source

pub fn new<SKS: Into<Option<SecretKeyShare>>, V: Into<ValidatorSet<N>>>( our_id: N, secret_key_share: SKS, public_key_set: PublicKeySet, val_set: V, ) -> Self

Creates a new NetworkInfo with the given ID and keys.

All nodes in the network must share the same public information. Validators’ IDs must be keys in the public_keys map, and their secret key share must match their share in the public_key_set.

§Panics

Panics if public_keys is empty or the requirement above is not satisfied, i.e. if the secret key doesn’t match the public key or is missing.

Source

pub fn our_id(&self) -> &N

The ID of the node the algorithm runs on.

Source

pub fn all_ids(&self) -> impl Iterator<Item = &N> + Clone

ID of all nodes in the network.

Source

pub fn other_ids(&self) -> impl Iterator<Item = &N> + Clone

ID of all nodes in the network except this one.

Source

pub fn num_nodes(&self) -> usize

The total number N of nodes.

Source

pub fn num_faulty(&self) -> usize

The maximum number f of faulty, Byzantine nodes up to which Honey Badger is guaranteed to be correct.

Source

pub fn num_correct(&self) -> usize

The minimum number N - f of correct nodes with which Honey Badger is guaranteed to be correct.

Source

pub fn secret_key_share(&self) -> Option<&SecretKeyShare>

Returns our secret key share for threshold cryptography, or None if not a validator.

Source

pub fn public_key_set(&self) -> &PublicKeySet

Returns the public key set for threshold cryptography.

Source

pub fn public_key_share(&self, id: &N) -> Option<&PublicKeyShare>

Returns the public key share if a node with that ID exists, otherwise None.

Source

pub fn public_key_share_map(&self) -> &BTreeMap<N, PublicKeyShare>

Returns a map of all node IDs to their public key shares.

Source

pub fn node_index(&self, id: &N) -> Option<usize>

The index of a node in a canonical numbering of all nodes. This is the index where the node appears in all_ids.

Source

pub fn is_validator(&self) -> bool

Returns true if this node takes part in the consensus itself. If not, it is only an observer.

Source

pub fn is_node_validator(&self, id: &N) -> bool

Returns true if the given node takes part in the consensus itself. If not, it is only an observer.

Source

pub fn validator_set(&self) -> &Arc<ValidatorSet<N>>

Returns the set of validator IDs.

Source

pub fn generate_map<I, R>( ids: I, rng: &mut R, ) -> Result<BTreeMap<N, NetworkInfo<N>>, Error>
where I: IntoIterator<Item = N>, R: Rng,

Generates a map of matching NetworkInfos for testing.
