Struct TxPool

Source 
pub struct TxPool<T: TransactionOrdering> { /* private fields */ }
Expand description

A pool that manages transactions.

This pool maintains the state of all transactions and stores them accordingly.

Implementations§

Source§

impl<T: TransactionOrdering> TxPool<T>

Source

pub fn new(ordering: T, config: PoolConfig) -> Self

Source

pub fn get_highest_transaction_by_sender( &self, sender: SenderId, ) -> Option<Arc<ValidPoolTransaction<T::Transaction>>>

Asserts all invariants of the pool’s:

  • All maps are bijections (by_id, by_hash)
  • Total size is equal to the sum of all sub-pools
§Panics

if any invariant is violated

Source§

impl TxPool<MockOrdering>

Source

pub fn mock() -> Self
