Fields

block_header: BlockHeader

The block header

nonce: u64

The nonce for use in short id calculation

tx_short_ids: Vec<u8>

A list of tx short ids

reconstructed_txns: Vec<Option<Arc<SignedTransaction>>>

Store the txns reconstructed, None means not received

Implementations

Trait Implementations

impl Clone for CompactBlock

fn clone(&self) -> CompactBlock

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for CompactBlock

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Decodable for CompactBlock

fn decode(rlp: &Rlp<'_>) -> Result<Self, DecoderError>

Decode a value from RLP bytes

impl Encodable for CompactBlock

fn rlp_append(&self, steam: &mut RlpStream)

Append a value to the stream

fn rlp_bytes(&self) -> Vec<u8>

Get rlp-encoded bytes for this instance

impl MallocSizeOf for CompactBlock

fn size_of(&self, ops: &mut MallocSizeOfOps) -> usize

Measure the heap usage of all descendant heap-allocated structures, but not the space taken up by the value itself.

impl PartialEq for CompactBlock

fn eq(&self, other: &CompactBlock) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
