Struct solana::bank::Bank

pub struct Bank {
    pub is_leader: bool,
    // some fields omitted
}

The state of all accounts and contracts after processing its entries.

Fields

is_leader: bool

This bool allows us to submit metrics that are specific for leaders or validators It is set to true by fullnode before creating the bank.

Methods

impl Bank

pub fn new_default(is_leader: bool) -> Self

Create a default Bank

pub fn new_from_deposit(deposit: &Payment) -> Self

Create an Bank using a deposit.

pub fn new(mint: &Mint) -> Self

Create an Bank with only a Mint. Typically used by unit tests.

pub fn last_id(&self) -> Hash

Return the last entry ID registered.

pub fn clear_signatures(&self)

Forget all signatures. Useful for benchmarking.

pub fn count_valid_ids(&self, ids: &[Hash]) -> Vec<(usize, u64)>

Look through the last_ids and find all the valid ids This is batched to avoid holding the lock for a significant amount of time

Return a vec of tuple of (valid index, timestamp) index is into the passed ids slice to avoid copying hashes

pub fn register_entry_id(&self, last_id: &Hash)

Tell the bank which Entry IDs exist on the ledger. This function assumes subsequent calls correspond to later entries, and will boot the oldest ones once its internal cache is full. Once boot, the bank will reject transactions using that last_id.

pub fn process_transaction(&self, tx: &Transaction) -> Result<()>

Process a Transaction. If it contains a payment plan that requires a witness to progress, the payment plan will be stored in the bank.

pub fn process_transactions(     &self,     txs: Vec<Transaction> ) -> Vec<Result<Transaction>>

Process a batch of transactions.

pub fn process_entry(&self, entry: Entry) -> Result<()>

pub fn process_entries(&self, entries: Vec<Entry>) -> Result<u64>

Process an ordered list of entries.

pub fn process_ledger<I>(&self, entries: I) -> Result<(u64, Vec<Entry>)> where     I: IntoIterator<Item = Entry>,

Process a full ledger.

pub fn transfer(     &self,     n: i64,     keypair: &Keypair,     to: Pubkey,     last_id: Hash ) -> Result<Signature>

Create, sign, and process a Transaction from keypair to to of n tokens where last_id is the last Entry ID observed by the client.

pub fn transfer_on_date(     &self,     n: i64,     keypair: &Keypair,     to: Pubkey,     dt: DateTime<Utc>,     last_id: Hash ) -> Result<Signature>

Create, sign, and process a postdated Transaction from keypair to to of n tokens on dt where last_id is the last Entry ID observed by the client.

pub fn get_balance(&self, pubkey: &Pubkey) -> i64

pub fn transaction_count(&self) -> usize

pub fn has_signature(&self, signature: &Signature) -> bool

pub fn finality(&self) -> usize

pub fn set_finality(&self, finality: usize)

Trait Implementations

fn default() -> Self
