hopr_chain_actions::action_queue

Struct ActionQueue

Source 
pub struct ActionQueue<Db, S, TxExec>
where
    Db: HoprDbInfoOperations + HoprDbTicketOperations + Send + Sync,
    S: ActionState + Send + Sync,
    TxExec: TransactionExecutor + Send + Sync,
{ /* private fields */ }
Expand description

A queue of Actions to be executed.

This queue awaits new Actions to arrive, translates them into Ethereum transactions via TransactionExecutor to execute them and await their confirmation by registering their corresponding expectations in ActionState.

impl<Db, S, TxExec> ActionQueue<Db, S, TxExec>
where Db: HoprDbInfoOperations + HoprDbTicketOperations + Clone + Send + Sync + 'static, S: ActionState + Send + Sync + 'static, TxExec: TransactionExecutor + Send + Sync + 'static,

Source

pub const ACTION_QUEUE_SIZE: usize = 2_048usize

Number of pending transactions in the queue

Source

pub fn new( db: Db, action_state: S, tx_exec: TxExec, cfg: ActionQueueConfig, ) -> Self

Creates a new instance with the given TransactionExecutor and ActionState implementations.

Source

pub fn new_sender(&self) -> ActionSender

Creates a new producer of actions for this queue.

Source

pub fn action_state(&self) -> Arc<S>

Source

pub async fn start(self)

Consumes self and runs the main queue processing loop until the queue is closed.

The method will panic if the Channel Domain Separator is not yet populated in the DB.
