Required Associated Types§

Source

type Connection: Send + Sync + Clone

Source

type Pool: Send + Sync + DatabasePool<Connection = Self::Connection, Error = Self::Error>

Source

type Error: Send + Sync + Clone + From<String> + Display + Debug

Required Methods§

Source

fn new<'async_trait>( config: DatabaseConfig, ) -> Pin<Box<dyn Future<Output = Result<Self, Self::Error>> + Send + 'async_trait>>
where Self: 'async_trait,

Source

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

Create a new connection pool for the given database

Source

fn connect_with_string<'life0, 'life1, 'async_trait>( &'life0 self, connection_string: &'life1 str, ) -> Pin<Box<dyn Future<Output = Result<Self::Connection, Self::Error>> + Send + 'async_trait>>
where 'life0: 'async_trait, 'life1: 'async_trait, Self: 'async_trait,

Create a single connection using a connection string directly This is useful for connecting to databases that may not have been created by TestKit

Source

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

Create a new database with the given name

Source

fn drop_database(&self, name: &DatabaseName) -> Result<(), Self::Error>

Drop a database with the given name

Source

fn connection_string(&self, name: &DatabaseName) -> String

Get the connection string for the given database

Provided Methods§

Source

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

Create a single connection to the given database This is useful for cases where a full pool is not needed

Dyn Compatibility§

This trait is not dyn compatible.

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