Implementations§

source§

impl ValidTransactionManagerStatus

source

pub fn transaction_depth(&self) -> Option<NonZeroU32>

This value is None if no current transaction is running otherwise the number of nested transactions is returned.

source

pub fn change_transaction_depth( &mut self, transaction_depth_change: TransactionDepthChange, ) -> QueryResult<()>

Update the transaction depth by adding the value of the transaction_depth_change parameter if the query is Ok(())
