Struct OpenTransaction

Source 
pub struct OpenTransaction(/* private fields */);
Expand description

Represents an already opened transaction. This is a thin wrapper over DatabaseTransaction. The wrapping behavior is needed to allow transaction agnostic functionalities of the DB traits.

Implementations§

Source§

impl OpenTransaction

Source

pub async fn perform<F, T, E>(self, callback: F) -> Result<T, E>
where F: for<'c> FnOnce(&'c OpenTransaction) -> BoxFuture<'c, Result<T, E>> + Send, T: Send, E: Error + From<DbSqlError>,

Executes the given callback inside the transaction and commits the transaction if it succeeds or rollbacks otherwise.

Source

pub async fn commit(self) -> Result<()>

Commits the transaction.

Source

pub async fn rollback(self) -> Result<()>

Rollbacks the transaction.
