Struct sn_routing::SectionProofChain

pub struct SectionProofChain { /* fields omitted */ }

Chain of section BLS keys where every key is proven (signed) by the previous key, except the first one.

Implementations

impl SectionProofChain

pub fn new(first: PublicKey) -> Self

Creates new chain consisting of only one block.

pub fn first_key(&self) -> &PublicKey

Returns the first key of the chain.

pub fn last_key(&self) -> &PublicKey

Returns the last key of the chain.

pub fn keys(&self) -> impl DoubleEndedIterator<Item = &PublicKey>

Returns all the keys of the chain as a DoubleEndedIterator.

pub fn has_key(&self, key: &PublicKey) -> bool

Returns whether this chain contains the given key.

pub fn index_of(&self, key: &PublicKey) -> Option<u64>

Returns the index of the key in the chain or None if not present in the chain.

pub fn slice<B: RangeBounds<u64>>(&self, range: B) -> Self

Returns a subset of this chain specified by the given index range.

Note: unlike std::slice, if the range is invalid or out of bounds, it is silently adjusted to the nearest valid range and so this function never panics.

pub fn len(&self) -> usize

Number of blocks in the chain (including the first block)

pub fn last_key_index(&self) -> u64

Index of the last key in the chain.

pub fn self_verify(&self) -> bool

Check that all the blocks in the chain except the first one have valid signatures. The first one cannot be verified and requires matching against already trusted keys. Thus this function alone cannot be used to determine whether this chain is trusted. Use check_trust for that.

pub fn check_trust<'a, I>(&self, trusted_keys: I) -> TrustStatus where
    I: IntoIterator<Item = &'a PublicKey>, 

Verify this proof chain against the given trusted keys.

Trait Implementations

impl Clone for SectionProofChain

fn clone(&self) -> SectionProofChain

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for SectionProofChain

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for SectionProofChain

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error> where

impl Eq for SectionProofChain

impl Hash for SectionProofChain

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

pub fn hash_slice<H>(data: &[Self], state: &mut H) where
    H: Hasher, 

Feeds a slice of this type into the given Hasher.
