Trait Implementations

impl Clone for PostgresBackend

fn clone(&self) -> PostgresBackend

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl DatabaseBackend for PostgresBackend

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 Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait,

Create a new connection pool for the given database

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 Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

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

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 Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Create a single connection using a connection string directly

type Connection = PostgresConnection

type Pool = PostgresPool

type Error = PostgresError

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

where Self: 'async_trait,

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 Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait,

Create a new database with the given name

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

Drop a database with the given name

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

Get the connection string for the given database

impl Debug for PostgresBackend

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
