Struct 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 address
2. Detect a spend of your Shielded notes
3. Update your witnesses to generate new 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

impl CompactBlock

pub fn from_block( block: &Block, hash: Hash, height: Height, sapling_tree_size: u64, orchard_tree_size: u64, ironwood_tree_size: u64, nullifiers_only: bool, ) -> Self

Builds a CompactBlock from a full block and the note commitment tree sizes at the end of that block.

If nullifiers_only is true, compact outputs are omitted and compact actions only contain nullifiers, matching the lightwalletd GetBlockNullifiers and GetBlockRangeNullifiers methods.

Trait Implementations

impl Clone for CompactBlock

fn clone(&self) -> CompactBlock

Returns a duplicate 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

Equality operator ==.

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

Inequality operator !=.

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
