Struct diem_sdk::types::proof::TransactionListProof

pub struct TransactionListProof {
    pub ledger_info_to_transaction_infos_proof: AccumulatorRangeProof<TransactionAccumulatorHasher>,
    pub transaction_infos: Vec<TransactionInfo, Global>,
}

The complete proof used to authenticate a list of consecutive transactions.

Fields

ledger_info_to_transaction_infos_proof: AccumulatorRangeProof<TransactionAccumulatorHasher>

The accumulator range proof from ledger info root to leaves that authenticates the hashes of all TransactionInfo objects.

transaction_infos: Vec<TransactionInfo, Global>

The TransactionInfo objects that correspond to all the transactions.

Implementations

impl TransactionListProof

pub fn new( ledger_info_to_transaction_infos_proof: AccumulatorRangeProof<TransactionAccumulatorHasher>, transaction_infos: Vec<TransactionInfo, Global> ) -> TransactionListProof

Constructs a new TransactionListProof using ledger_info_to_transaction_info_proof and transaction_infos.

pub fn new_empty() -> TransactionListProof

Constructs a proof for an empty list of transactions.

pub fn transaction_infos(&self) -> &[TransactionInfo]

Returns the list of TransactionInfo objects.

pub fn left_siblings(&self) -> &Vec<HashValue, Global>

pub fn unpack( self ) -> (AccumulatorRangeProof<TransactionAccumulatorHasher>, Vec<TransactionInfo, Global>)

pub fn verify( &self, ledger_info: &LedgerInfo, first_transaction_version: Option<u64>, transaction_hashes: &[HashValue] ) -> Result<(), Error>

Verifies the list of transactions are correct using the proof. The verifier needs to have the ledger info and the version of the first transaction in possession.

Trait Implementations

impl Arbitrary for TransactionListProof

type Parameters = (<AccumulatorRangeProof<TransactionAccumulatorHasher> as Arbitrary>::Parameters, <Vec<TransactionInfo, Global> as Arbitrary>::Parameters)

The type of parameters that arbitrary_with accepts for configuration of the generated Strategy. Parameters must implement Default.

type Strategy = Map<(<AccumulatorRangeProof<TransactionAccumulatorHasher> as Arbitrary>::Strategy, <Vec<TransactionInfo, Global> as Arbitrary>::Strategy), fn(_: (AccumulatorRangeProof<TransactionAccumulatorHasher>, Vec<TransactionInfo, Global>)) -> TransactionListProof>

The type of Strategy used to generate values of type Self.

fn arbitrary_with( _top: <TransactionListProof as Arbitrary>::Parameters ) -> <TransactionListProof as Arbitrary>::Strategy

Generates a Strategy for producing arbitrary values of type the implementing type (Self). The strategy is passed the arguments given in args.

fn arbitrary() -> Self::Strategy

Generates a Strategy for producing arbitrary values of type the implementing type (Self).

impl Clone for TransactionListProof

fn clone(&self) -> TransactionListProof

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for TransactionListProof

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for TransactionListProof

fn deserialize<__D>( __deserializer: __D ) -> Result<TransactionListProof, <__D as Deserializer<'de>>::Error>where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq<TransactionListProof> for TransactionListProof

fn eq(&self, other: &TransactionListProof) -> 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.

impl Serialize for TransactionListProof

fn serialize<__S>( &self, __serializer: __S ) -> Result<<__S as Serializer>::Ok, <__S as Serializer>::Error>where __S: Serializer,

Serialize this value into the given Serde serializer.

impl TryFrom<&TransactionListProof> for TransactionsProofsView

Performs the conversion.

impl TryFrom<&TransactionsProofsView> for TransactionListProof

type Error = Error

The type returned in the event of a conversion error.

fn try_from( view: &TransactionsProofsView ) -> Result<TransactionListProof, <TransactionListProof as TryFrom<&TransactionsProofsView>>::Error>

Performs the conversion.
