Struct Transaction 

pub struct Transaction<'a> { /* private fields */ }

A transaction for atomic operations on a symbol table.

Transactions capture the state of the symbol table at the start and allow rolling back to that state if needed.

Implementations

impl<'a> Transaction<'a>

pub fn execute<F, R>(&mut self, f: F) -> Result<R, AdapterError>

where F: FnOnce(&mut SymbolTable) -> Result<R, AdapterError>,

Execute operations within this transaction.

The closure receives a mutable reference to the symbol table.

pub fn commit(self)

Commit the transaction, making all changes permanent.

pub fn rollback(self)

Rollback the transaction, reverting all changes.
