All chain-related database operations
Implementations
sourceimpl ChainStore
impl ChainStore
sourcepub fn header_head(&self) -> Result<Tip, Error>
pub fn header_head(&self) -> Result<Tip, Error>
The current header head (may differ from chain head).
sourcepub fn tail(&self) -> Result<Tip, Error>
pub fn tail(&self) -> Result<Tip, Error>
The current chain “tail” (earliest block in the store).
sourcepub fn head_header(&self) -> Result<BlockHeader, Error>
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).
sourcepub fn get_block_sums(&self, h: &Hash) -> Result<BlockSums, Error>
pub fn get_block_sums(&self, h: &Hash) -> Result<BlockSums, Error>
Get block_sums for the block hash.
sourcepub fn get_previous_header(
&self,
header: &BlockHeader
) -> Result<BlockHeader, Error>
pub fn get_previous_header(
&self,
header: &BlockHeader
) -> Result<BlockHeader, Error>
Get previous header.
sourcepub fn get_previous_header_skip_proof(
&self,
header: &BlockHeader
) -> Result<BlockHeader, Error>
pub fn get_previous_header_skip_proof(
&self,
header: &BlockHeader
) -> Result<BlockHeader, Error>
Get previous header without deserializing the proof nonces
sourcepub fn get_block_header(&self, h: &Hash) -> Result<BlockHeader, Error>
pub fn get_block_header(&self, h: &Hash) -> Result<BlockHeader, Error>
Get block header.
sourcepub fn get_block_header_skip_proof(
&self,
h: &Hash
) -> Result<BlockHeader, Error>
pub fn get_block_header_skip_proof(
&self,
h: &Hash
) -> Result<BlockHeader, Error>
Get block header without deserializing the full PoW Proof; currently used for difficulty iterator which is called many times but doesn’t need the proof
sourcepub fn get_output_pos(&self, commit: &Commitment) -> Result<u64, Error>
pub fn get_output_pos(&self, commit: &Commitment) -> Result<u64, Error>
Get PMMR pos for the given output commitment.

fn borrow_replacement(ptr: &T) -> &T
fn borrow_replacement(ptr: &T) -> &T
Given ptr, which was obtained from a prior call to Self::borrow(),
return a value with the same nominal lifetime which is guaranteed to
survive mutations to Self. Read more
