Struct TransactionsManager 

Source 
pub struct TransactionsManager<Pool, N: NetworkPrimitives = EthNetworkPrimitives, P: TransactionPropagationPolicy = TransactionPropagationKind> { /* private fields */ }
Expand description

Manages transactions on top of the p2p network.

This can be spawned to another task and is supposed to be run as background service. TransactionsHandle can be used as frontend to programmatically send commands to it and interact with it.

The TransactionsManager is responsible for:

  • handling incoming eth messages for transactions.
  • serving transaction requests.
  • propagate transactions

This type communicates with the NetworkManager in both directions.

  • receives incoming network messages.
  • sends messages to dispatch (responses, propagate tx)

It is directly connected to the [TransactionPool] to retrieve requested transactions and propagate new transactions over the network.

Implementations§

Source§

impl<Pool: TransactionPool, N: NetworkPrimitives> TransactionsManager<Pool, N>

Source

pub fn new( network: NetworkHandle<N>, pool: Pool, from_network: UnboundedReceiver<NetworkTransactionEvent<N>>, transactions_manager_config: TransactionsManagerConfig, ) -> Self

Sets up a new instance.

Note: This expects an existing NetworkManager instance.

Source§

impl<Pool: TransactionPool, N: NetworkPrimitives, P: TransactionPropagationPolicy> TransactionsManager<Pool, N, P>

Source

pub fn with_policy( network: NetworkHandle<N>, pool: Pool, from_network: UnboundedReceiver<NetworkTransactionEvent<N>>, transactions_manager_config: TransactionsManagerConfig, propagation_policy: P, ) -> Self

Sets up a new instance with given the settings.

Note: This expects an existing NetworkManager instance.

Source

pub fn handle(&self) -> TransactionsHandle<N>

Returns a new handle that can send commands to this type.
