Struct Store 

pub struct Store<T> { /* private fields */ }

Implementation of ChainStore using pure_stage::Effects.

Implementations

impl<T> Store<T>

pub fn new(effects: Effects<T>) -> Store<T>

pub fn external_sync<E: ExternalEffectSync + Serialize + 'static>( &self, effect: E, ) -> E::Response

This function runs an external effect synchronously.

Trait Implementations

impl<T: SendData + Sync> ChainStore<BlockHeader> for Store<T>

fn set_anchor_hash(&self, hash: &HeaderHash) -> Result<(), StoreError>

fn set_best_chain_hash(&self, hash: &HeaderHash) -> Result<(), StoreError>

fn store_header(&self, header: &BlockHeader) -> Result<(), StoreError>

fn store_block( &self, hash: &HeaderHash, block: &RawBlock, ) -> Result<(), StoreError>

fn put_nonces( &self, header: &HeaderHash, nonces: &Nonces, ) -> Result<(), StoreError>

fn roll_forward_chain(&self, point: &Point) -> Result<(), StoreError>

Roll forward the best chain to the given point.

fn rollback_chain(&self, point: &Point) -> Result<usize, StoreError>

Rollback the best chain tip at the given point. The point must exist on the best chain, and all points on chain after that point will be deleted. Returns the number of headers that were rolled back.

impl<T> Clone for Store<T>

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<T> ReadOnlyChainStore<BlockHeader> for Store<T>

fn load_header(&self, hash: &HeaderHash) -> Option<BlockHeader>

Try to load a header by its hash.

fn get_children(&self, hash: &HeaderHash) -> Vec<HeaderHash>

fn get_anchor_hash(&self) -> HeaderHash

fn get_best_chain_hash(&self) -> HeaderHash

fn load_block(&self, hash: &HeaderHash) -> Result<Option<RawBlock>, StoreError>

fn get_nonces(&self, hash: &HeaderHash) -> Option<Nonces>

fn has_header(&self, hash: &HeaderHash) -> bool

fn load_from_best_chain(&self, point: &Point) -> Option<HeaderHash>

Load a HeaderHash from the best chain. Returns None if the point is not in the best chain.

fn next_best_chain(&self, point: &Point) -> Option<Point>

Return the next Point on the best chain following given Point, if it exists.

fn load_tip( &self, hash: &Hash<amaru_kernel::::cardano::hash::HeaderHash::{constant#0}>, ) -> Option<Tip>

Retrieve the tip of a block header given its hash.

fn retrieve_best_chain( &self, ) -> Vec<Hash<amaru_kernel::::cardano::hash::HeaderHash::{constant#0}>>

Return the hashes of the best chain fragment, starting from the anchor.

fn ancestors<'a>(&'a self, start: H) -> Box<dyn Iterator<Item = H> + 'a>

where H: 'a,

Return the ancestors of the header, including the header itself. Stop if the followed chain reaches past the anchor.

fn ancestors_hashes<'a>( &'a self, hash: &Hash<amaru_kernel::::cardano::hash::HeaderHash::{constant#0}>, ) -> Box<dyn Iterator<Item = Hash<amaru_kernel::::cardano::hash::HeaderHash::{constant#0}>> + 'a>

where H: 'a,

Return the hashes of the ancestors of the header, including the header hash itself.
