Struct massa_execution_worker :: speculative_async_pool :: SpeculativeAsyncPool Copy item path

impl SpeculativeAsyncPool

pub fn new( final_state: Arc<RwLock<dyn FinalStateController>>, active_history: Arc<RwLock<ActiveHistory>>, ) -> Self

Creates a new SpeculativeAsyncPool

§Arguments

pub fn take(&mut self) -> AsyncPoolChanges

Returns the changes caused to the SpeculativeAsyncPool since its creation, and resets their local value to nothing. This must be called after settle_emitted_messages() The message_infos should already be removed if taken, no need to do it here.

pub fn get_snapshot( &self, ) -> (AsyncPoolChanges, BTreeMap<AsyncMessageId, AsyncMessage>)

Takes a snapshot (clone) of the emitted messages

pub fn reset_to_snapshot( &mut self, snapshot: (AsyncPoolChanges, BTreeMap<AsyncMessageId, AsyncMessage>), )

Resets the SpeculativeAsyncPool emitted messages to a snapshot (see get_snapshot method)

pub fn push_new_message(&mut self, msg: AsyncMessage)

Add a new message to the list of changes of this SpeculativeAsyncPool

pub fn take_batch_to_execute( &mut self, slot: Slot, max_gas: u64, async_msg_cst_gas_cost: u64, ) -> Vec<(AsyncMessageId, AsyncMessage)>

Takes a batch of asynchronous messages to execute, removing them from the speculative asynchronous pool and settling their deletion from it in the changes accumulator.

§Arguments

slot: slot at which the batch is taken (allows filtering by validity interval)
max_gas: maximum amount of gas available

§Returns

A vector of AsyncMessage to execute

pub fn settle_slot( &mut self, slot: &Slot, ledger_changes: &LedgerChanges, ) -> Vec<(AsyncMessageId, AsyncMessage)>

Settle a slot. Consume newly emitted messages into self.async_pool, recording changes into self.settled_changes.

§Arguments

slot: slot that is being settled
ledger_changes: ledger changes for that slot, used to see if we can activate some messages

§Returns

the list of deleted (message_id, message), used for reimbursement

fn delete_messages(&mut self, message_ids: Vec<AsyncMessageId>)

fn is_message_expired(slot: &Slot, message_validity_end: &Slot) -> bool

Return true if a message (given its validity end) is expired Must be consistent with is_message_valid

fn is_message_ready_to_execute( slot: &Slot, message_validity_start: &Slot, message_validity_end: &Slot, ) -> bool

Return true if a message (given its validity_start & validity end) is ready to execute Must be consistent with is_message_expired
