Trait Transaction 

pub trait Transaction: QueryExecutor {
    type Nested<'a>: Transaction<Error = Self::Error, Row = Self::Row> + 'a
       where Self: 'a;

    // Required methods
    fn transaction(
        &mut self,
    ) -> impl Future<Output = Result<Self::Nested<'_>, Self::Error>> + Send;
    fn commit(self) -> impl Future<Output = Result<(), Self::Error>> + Send;
    fn rollback(self) -> impl Future<Output = Result<(), Self::Error>> + Send;
}

Trait for a database transaction. Extends QueryExecutor with commit/rollback and nested transaction (savepoint) support. Dropping without calling commit() should rollback the transaction.

Required Associated Types

type Nested<'a>: Transaction<Error = Self::Error, Row = Self::Row> + 'a where Self: 'a

Required Methods

fn transaction( &mut self, ) -> impl Future<Output = Result<Self::Nested<'_>, Self::Error>> + Send

Begin a nested transaction (savepoint).

fn commit(self) -> impl Future<Output = Result<(), Self::Error>> + Send

Commit this transaction.

fn rollback(self) -> impl Future<Output = Result<(), Self::Error>> + Send

Rollback this transaction.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.

Implementors

impl Transaction for PgTransaction<'_>

type Nested<'a> = PgTransaction<'a> where Self: 'a
