Struct clarity_repl::clarity::clarity::ClarityBlockConnection

pub struct ClarityBlockConnection<'a> { /* fields omitted */ }

A high-level interface for Clarity VM interactions within a single block.

Implementations

impl<'_> ClarityBlockConnection<'_>

pub fn reset_block_cost(&mut self, cost: ExecutionCost)

Reset the block's total execution to the given cost, if there is a cost tracker at all. Used by the miner to "undo" applying a transaction that exceeded the budget.

pub fn cost_so_far(&self) -> ExecutionCost

Get the current cost so far

impl<'a> ClarityBlockConnection<'a>

pub fn rollback_block(self)

Rolls back all changes in the current block by (1) dropping all writes from the current MARF tip, (2) rolling back side-storage

pub fn commit_to_block(self, final_bhh: &StacksBlockId) -> LimitedCostTracker

Commits all changes in the current block by (1) committing the current MARF tip to storage, (2) committing side-storage. Commits all changes in the current block by (1) committing the current MARF tip to storage, (2) committing side-storage. Commits to a different block hash than the one opened (i.e. since the caller may not have known the "real" block hash at the time of opening).

pub fn commit_mined_block(self, bhh: &StacksBlockId) -> LimitedCostTracker

Commits all changes in the current block by (1) committing the current MARF tip to storage, (2) committing side-storage. before this saves, it updates the metadata headers in the sidestore so that they don't get stepped on after a miner re-executes a constructed block.

    &'b mut self
