Implementations

impl ChainStore

pub fn new(db_root: &str) -> Result<ChainStore, Error>

Create new chain store

pub fn head(&self) -> Result<Tip, Error>

The current chain head.

pub fn header_head(&self) -> Result<Tip, Error>

The current header head (may differ from chain head).

pub fn tail(&self) -> Result<Tip, Error>

The current chain “tail” (earliest block in the store).

pub fn head_header(&self) -> Result<BlockHeader, Error>

Header of the block at the head of the block chain (not the same thing as header_head).

pub fn get_block(&self, h: &Hash) -> Result<Block, Error>

Get full block.

pub fn block_exists(&self, h: &Hash) -> Result<bool, Error>

Does this full block exist?

pub fn get_block_sums(&self, h: &Hash) -> Result<BlockSums, Error>

Get block_sums for the block hash.

pub fn get_previous_header(
    &self,
    header: &BlockHeader
) -> Result<BlockHeader, Error>

Get previous header.

pub fn get_block_header(&self, h: &Hash) -> Result<BlockHeader, Error>

Get block header.

pub fn get_output_pos(&self, commit: &Commitment) -> Result<u64, Error>

Get PMMR pos for the given output commitment.

pub fn get_output_pos_height(
    &self,
    commit: &Commitment
) -> Result<Option<CommitPos>, Error>

Get PMMR pos and block height for the given output commitment.

pub fn batch(&self) -> Result<Batch<'_>, Error>

Builds a new batch to be used with this store.
