Expand description
CompactBlock is a packaging of ONLY the data from a block that’s needed to:
- Detect a payment to your shielded Sapling address
- Detect a spend of your shielded Sapling notes
- Update your witnesses to generate new Sapling spend proofs.
Fields§
§proto_version: u32
the version of this wire format, for storage
height: u64
the height of this block
hash: Vec<u8>
the ID (hash) of this block, same as in block explorers
prev_hash: Vec<u8>
the ID (hash) of this block’s predecessor
time: u32
Unix epoch time when the block was mined
header: Vec<u8>
(hash, prevHash, and time) OR (full header)
vtx: Vec<CompactTx>
zero or more compact transactions from this block
chain_metadata: Option<ChainMetadata>
information about the state of the chain as of this block
Implementations§
source§impl CompactBlock
impl CompactBlock
sourcepub fn hash(&self) -> BlockHash
pub fn hash(&self) -> BlockHash
Returns the BlockHash
for this block.
Panics
This function will panic if CompactBlock.header
is not set and
CompactBlock.hash
is not exactly 32 bytes.
sourcepub fn prev_hash(&self) -> BlockHash
pub fn prev_hash(&self) -> BlockHash
Returns the BlockHash
for this block’s parent.
Panics
This function will panic if CompactBlock.header
is not set and
CompactBlock.prevHash
is not exactly 32 bytes.
sourcepub fn height(&self) -> BlockHeight
pub fn height(&self) -> BlockHeight
Returns the BlockHeight
value for this block
Panics
This function will panic if [CompactBlock.height
] is not
representable within a u32.
sourcepub fn header(&self) -> Option<BlockHeader>
pub fn header(&self) -> Option<BlockHeader>
Returns the BlockHeader
for this block if present.
A convenience method that parses CompactBlock.header
if present.
