pub struct ValidTransactionManagerStatus { /* private fields */ }

Expand description

Valid transaction status for the manager. Can return the current transaction depth

Implementations

source

impl ValidTransactionManagerStatus

source

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

Return the current transaction depth

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(())
