Source

fn begin_transaction<'life0, 'async_trait>( &'life0 self, ) -> Pin<Box<dyn Future<Output = DatabaseResult<Box<dyn DatabaseTransaction>>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait,

Begin a transaction

Source

fn get_database_type(&self) -> DatabaseType

Get the underlying database type

Source

fn ping<'life0, 'async_trait>( &'life0 self, ) -> Pin<Box<dyn Future<Output = DatabaseResult<()>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait,

Source

fn close<'life0, 'async_trait>( &'life0 self, ) -> Pin<Box<dyn Future<Output = DatabaseResult<()>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait,

Dyn Compatibility§

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
