Trait DBBackend

pub trait DBBackend<'c, DB>
where
    DB: Database,
{
    // Required method
    fn backend_db(
        self,
    ) -> impl Future<Output = Result<(DBType, Either<impl Executor<'c, Database = DB>, PoolConnection<DB>>), Error>> + Send;
}

Trait for database connections/pools that can detect their backend type

Type Parameters

• 'c: Connection lifetime
• DB: Database type implementing [sqlx::Database]
• C1: Dereference target type (must be Any)

Required Implementations

Automatically implemented for types that:

• Implement Executor for database operations
• Implement Deref to an Any type

Provided Methods

backend_db: Default implementation using the module-level function

Required Methods

fn backend_db( self, ) -> impl Future<Output = Result<(DBType, Either<impl Executor<'c, Database = DB>, PoolConnection<DB>>), Error>> + Send

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<'c, DB, C, C1> DBBackend<'c, DB> for C

where DB: Database, C: Executor<'c, Database = DB> + 'c + Deref<Target = C1>, C1: Any,
