Struct ValidTransactionManagerStatus

Source
#[non_exhaustive]
pub struct ValidTransactionManagerStatus { pub in_transaction: Option<InTransactionStatus>, }
Available on crate feature i-implement-a-third-party-backend-and-opt-into-breaking-changes only.
Expand description

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

Fields (Non-exhaustive)§

This struct is marked as non-exhaustive
Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.
§in_transaction: Option<InTransactionStatus>

Inner status, or None if no transaction is running

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(())
