Struct BankHashProof

pub struct BankHashProof {
    pub parent_bankhash: Hash,
    pub blockhash: Hash,
    /* private fields */
}

The proof for a bankhash is simply its components.

It’s not very interesting on its own, but when combined with crate::accounts_delta_hash it can be used to prove the state of accounts at a particular slot.

Fields

parent_bankhash: Hash

The bankhash of the parent block. NOT the blockhash.

blockhash: Hash

The Proof-of-History tick after interleaving all the transactions in the block. NOT related to the bankhash.

Implementations

impl BankHashProof

pub fn new( parent_bankhash: Hash, accounts_delta_hash: Hash, signature_count: u64, blockhash: Hash, ) -> Self

Creates a bank hash proof.

pub fn verify(&self, bank_hash: Hash) -> bool

Verifies that the bankhash matches the expected value.

pub fn hash(&self) -> Hash

Hashes the components to create the bankhash.

Trait Implementations

impl Clone for BankHashProof

fn clone(&self) -> BankHashProof

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for BankHashProof

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for BankHashProof

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for BankHashProof

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

Tests for self and other values to be equal, and is used by ==.

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

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

impl Serialize for BankHashProof

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
