Required Methods

fn open( &mut self, address: String, ) -> impl Future<Output = Result<Resource<Connection>, Error>> + Send

Open a connection to the Postgres instance at address.

fn query( &mut self, self_: Resource<Connection>, statement: String, params: Vec<ParameterValue>, ) -> impl Future<Output = Result<RowSet, Error>> + Send

Query the database.

fn execute( &mut self, self_: Resource<Connection>, statement: String, params: Vec<ParameterValue>, ) -> impl Future<Output = Result<u64, Error>> + Send

Execute command to the database.

fn drop( &mut self, rep: Resource<Connection>, ) -> impl Future<Output = Result<()>> + 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.
