Struct zaino_proto::proto::compact_formats::CompactBlock

pub struct CompactBlock {
    pub proto_version: u32,
    pub height: u64,
    pub hash: Vec<u8>,
    pub prev_hash: Vec<u8>,
    pub time: u32,
    pub header: Vec<u8>,
    pub vtx: Vec<CompactTx>,
    pub chain_metadata: Option<ChainMetadata>,
}

A compact representation of the shielded data in a Zcash block.

CompactBlock is a packaging of ONLY the data from a block that’s needed to:

1. Detect a payment to your shielded Sapling address
2. Detect a spend of your shielded Sapling notes
3. 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

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 Default for CompactBlock

fn default() -> Self

Returns the “default value” for a type.

impl Message for CompactBlock

fn encoded_len(&self) -> usize

Returns the encoded length of the message without a length delimiter.

fn clear(&mut self)

Clears the message, resetting all fields to their default.

fn encode(&self, buf: &mut impl BufMut) -> Result<(), EncodeError>

where Self: Sized,

Encodes the message to a buffer.

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

where Self: Sized,

Encodes the message to a newly allocated buffer.

fn encode_length_delimited( &self, buf: &mut impl BufMut, ) -> Result<(), EncodeError>

where Self: Sized,

Encodes the message with a length-delimiter to a buffer.

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

where Self: Sized,

Encodes the message with a length-delimiter to a newly allocated buffer.

fn decode(buf: impl Buf) -> Result<Self, DecodeError>

where Self: Default,

Decodes an instance of the message from a buffer.

fn decode_length_delimited(buf: impl Buf) -> Result<Self, DecodeError>

where Self: Default,

Decodes a length-delimited instance of the message from the buffer.

fn merge(&mut self, buf: impl Buf) -> Result<(), DecodeError>

where Self: Sized,

Decodes an instance of the message from a buffer, and merges it into self.

fn merge_length_delimited(&mut self, buf: impl Buf) -> Result<(), DecodeError>

where Self: Sized,

Decodes a length-delimited instance of the message from buffer, and merges it into self.

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.
