Implementations§
Source§impl BlockchainOverlay
impl BlockchainOverlay
Sourcepub fn new(blockchain: &Blockchain) -> Result<BlockchainOverlayPtr>
pub fn new(blockchain: &Blockchain) -> Result<BlockchainOverlayPtr>
Instantiate a new BlockchainOverlay
over the given Blockchain
instance.
Sourcepub fn last(&self) -> Result<(u32, HeaderHash)>
pub fn last(&self) -> Result<(u32, HeaderHash)>
Retrieve the last block height and hash.
Sourcepub fn last_block(&self) -> Result<BlockInfo>
pub fn last_block(&self) -> Result<BlockInfo>
Retrieve the last block info.
Sourcepub fn last_block_height(&self) -> Result<u32>
pub fn last_block_height(&self) -> Result<u32>
Retrieve the last block height.
Sourcepub fn last_block_timestamp(&self) -> Result<Timestamp>
pub fn last_block_timestamp(&self) -> Result<Timestamp>
Retrieve the last block timestamp.
Sourcepub fn add_block(&self, block: &BlockInfo) -> Result<HeaderHash>
pub fn add_block(&self, block: &BlockInfo) -> Result<HeaderHash>
Insert a given BlockInfo
into the overlay.
This functions wraps all the logic of separating the block into specific
data that can be fed into the different trees of the overlay.
Upon success, the functions returns the block hash that
were given and appended to the overlay.
Since we are adding to the overlay, we don’t need to exeucte
the writes atomically.
Sourcepub fn has_block(&self, block: &BlockInfo) -> Result<bool>
pub fn has_block(&self, block: &BlockInfo) -> Result<bool>
Check if the given BlockInfo
is in the database and all trees.
Sourcepub fn get_headers_by_hash(&self, hashes: &[HeaderHash]) -> Result<Vec<Header>>
pub fn get_headers_by_hash(&self, hashes: &[HeaderHash]) -> Result<Vec<Header>>
Retrieve Header
s by given hashes. Fails if any of them is not found.
Sourcepub fn get_blocks_by_hash(
&self,
hashes: &[HeaderHash],
) -> Result<Vec<BlockInfo>>
pub fn get_blocks_by_hash( &self, hashes: &[HeaderHash], ) -> Result<Vec<BlockInfo>>
Retrieve BlockInfo
s by given hashes. Fails if any of them is not found.
Sourcepub fn get_blocks_txs_hashes(
&self,
hashes: &[HeaderHash],
) -> Result<Vec<TransactionHash>>
pub fn get_blocks_txs_hashes( &self, hashes: &[HeaderHash], ) -> Result<Vec<TransactionHash>>
Retrieve Block
s by given hashes and return their transactions hashes.
Sourcepub fn checkpoint(&self)
pub fn checkpoint(&self)
Checkpoint overlay so we can revert to it, if needed.
Sourcepub fn revert_to_checkpoint(&self) -> Result<()>
pub fn revert_to_checkpoint(&self) -> Result<()>
Revert to current overlay checkpoint.
Sourcepub fn full_clone(&self) -> Result<BlockchainOverlayPtr>
pub fn full_clone(&self) -> Result<BlockchainOverlayPtr>
Auxiliary function to create a full clone using SledDbOverlay::clone, generating new pointers for the underlying overlays.
