Struct trust_graph::TrustGraph

pub struct TrustGraph<S> where
    S: Storage,  { /* fields omitted */ }

Graph to efficiently calculate weights of certificates and get chains of certificates. TODO serialization/deserialization TODO export a certificate from graph

Implementations

impl<S> TrustGraph<S> where
    S: Storage, 

pub fn new(storage: S) -> Self

pub fn add_root_weight(
    &mut self,
    pk: PK,
    weight: Weight
) -> Result<(), TrustGraphError>

Insert new root weight

pub fn get(&self, pk: PublicKey) -> Result<Option<TrustNode>, TrustGraphError>

Get trust by public key

pub fn add<C>(
    &mut self,
    cert: C,
    cur_time: Duration
) -> Result<(), TrustGraphError> where
    C: Borrow<Certificate>, 

Certificate is a chain of trusts, add this chain to graph

pub fn weight<P>(&self, pk: P) -> Result<Option<Weight>, TrustGraphError> where
    P: Borrow<PublicKey>, 

Get the maximum weight of trust for one public key.

pub fn certificates_weight<C, I>(
    &self,
    certs: I
) -> Result<Option<Weight>, TrustGraphError> where
    C: Borrow<Certificate>,
    I: IntoIterator<Item = C>, 

Calculate weight from given certificates Returns None if there is no such public key or some trust between this key and a root key is revoked. TODO handle non-direct revocations

pub fn get_all_certs<P>(
    &self,
    issued_for: P,
    roots: &[PublicKey]
) -> Result<Vec<Certificate>, TrustGraphError> where
    P: Borrow<PublicKey>, 

Get all possible certificates where issued_for will be the last element of the chain and one of the destinations is the root of this chain.

pub fn revoke(&mut self, revoke: Revoke) -> Result<(), TrustGraphError>

Mark public key as revoked.
