Struct Beef 

pub struct Beef {
    pub version: u32,
    pub bumps: Vec<MerklePath>,
    pub transactions: HashMap<Hash, BeefTx>,
}

A set of Transactions and their MerklePaths (BUMPs).

Fields

version: u32

BEEF version number (e.g. BEEF_V1 or BEEF_V2).

bumps: Vec<MerklePath>

Merkle paths (BUMPs) proving transaction inclusion in blocks.

transactions: HashMap<Hash, BeefTx>

Transactions keyed by their txid hash.

Implementations

impl Beef

pub fn new() -> Self

Create a new empty BEEF V2.

pub fn new_v1() -> Self

Create a new empty BEEF V1.

pub fn new_v2() -> Self

Create a new empty BEEF V2.

pub fn from_hex(hex_str: &str) -> Result<Self, SpvError>

Parse a BEEF from a hex string.

pub fn from_bytes(data: &[u8]) -> Result<Self, SpvError>

Parse a BEEF from bytes.

pub fn to_bytes(&self) -> Result<Vec<u8>, SpvError>

Serialize this BEEF to bytes (V2 format).

pub fn to_hex(&self) -> Result<String, SpvError>

Serialize to hex.

pub fn find_transaction(&self, txid: &str) -> Option<&Transaction>

Find a transaction by txid hex string.

pub fn find_bump(&self, txid: &str) -> Option<&MerklePath>

Find a BUMP by txid.

pub fn find_bump_by_hash(&self, txid: &Hash) -> Option<&MerklePath>

Find a BUMP by txid hash.

pub fn merge_bump(&mut self, bump: &MerklePath) -> Result<usize, SpvError>

Merge a BUMP, returning its index in the bumps array.

pub fn is_valid(&self, allow_txid_only: bool) -> bool

Check if the BEEF is valid (all transactions traceable to BUMPs).

pub fn verify( &self, chain_tracker: &dyn ChainTracker, allow_txid_only: bool, ) -> Result<bool, SpvError>

Verify the BEEF against a chain tracker.
