Expand description

A trait for database backends that can create and manage databases

Required Associated Types§

Source

type Connection: Connection

The type of connection this backend provides

Source

type Pool: DatabasePool<Connection = Self::Connection>

The type of pool this backend provides

Required Methods§

Source

fn create_database<'life0, 'life1, 'async_trait>( &'life0 self, name: &'life1 DatabaseName, ) -> Pin<Box<dyn Future<Output = Result<()>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Create a new database with the given name

Source

fn drop_database<'life0, 'life1, 'async_trait>( &'life0 self, name: &'life1 DatabaseName, ) -> Pin<Box<dyn Future<Output = Result<()>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Drop a database with the given name

Source

fn create_pool<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, name: &'life1 DatabaseName, config: &'life2 PoolConfig, ) -> Pin<Box<dyn Future<Output = Result<Self::Pool>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait,

Create a new connection pool for the given database

Source

fn terminate_connections<'life0, 'life1, 'async_trait>( &'life0 self, name: &'life1 DatabaseName, ) -> Pin<Box<dyn Future<Output = Result<()>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Terminate all connections to the given database

Source

fn create_database_from_template<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, name: &'life1 DatabaseName, template: &'life2 DatabaseName, ) -> Pin<Box<dyn Future<Output = Result<()>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait,

Create a new database from a template

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.
