Struct TransactionManager 

pub struct TransactionManager { /* private fields */ }

Transaction manager combining execution, persistence, and validation

Implementations

impl TransactionManager

pub fn new(node_id: String, initial_version: StateVersion) -> Self

Create a new transaction manager

pub fn current_state_version(&self) -> StateVersion

Get the current state version

pub fn execute_and_commit( &mut self, transaction_id: String, operations: Vec<Operation>, consistency_contract: ConsistencyContract, ) -> TxResult<StateTransitionRecord>

Execute a transaction with full persistence integration

pub fn get_operation( &self, operation_id: &OperationId, ) -> Option<OperationLogEntry>

Get a recorded operation by ID

pub fn get_transition( &self, transaction_id: &str, ) -> Option<StateTransitionRecord>

Get a recorded transition by transaction ID

pub fn operation_log_size(&self) -> u64

Get the operation log size

pub fn transition_store_size(&self) -> u64

Get the transition store size

pub fn rebuild_from_operation_log(&mut self) -> TxResult<StateVersion>

Rebuild state from operation log (for recovery) Executes all operations in order to verify state integrity

pub fn get_transition_chain_from( &self, from_state_hash: &str, ) -> Vec<StateTransitionRecord>

Get the chain of state transitions from a starting version

pub fn validate_preconditions(&self, operation: &Operation) -> TxResult<()>

Validate preconditions for an operation (Simple string matching - production would have actual condition evaluation)
