Struct diesel::connection::ValidTransactionManagerStatus
source · pub struct ValidTransactionManagerStatus { /* private fields */ }Expand description
Valid transaction status for the manager. Can return the current transaction depth
Implementations§
source§impl ValidTransactionManagerStatus
impl ValidTransactionManagerStatus
sourcepub fn transaction_depth(&self) -> Option<NonZeroU32>
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.
sourcepub fn change_transaction_depth(
&mut self,
transaction_depth_change: TransactionDepthChange
) -> QueryResult<()>
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(())
