Trait HostConnection 

pub trait HostConnection: Send {
    // Required methods
    fn open(
        &mut self,
        database: String,
    ) -> impl Future<Output = Result<Resource<Connection>, Error>> + Send;

}

Required Methods

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

Open a connection to a named database instance.

If database is “default”, the default instance is opened.

error::no-such-database will be raised if the name is not recognized.

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

Execute a statement returning back data if there is any

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".

Implementations on Foreign Types

impl<_T: HostConnection + ?Sized + Send> HostConnection for &mut _T

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

Open a connection to a named database instance.

If database is “default”, the default instance is opened.

error::no-such-database will be raised if the name is not recognized.

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

Execute a statement returning back data if there is any

async fn drop(&mut self, rep: Resource<Connection>) -> Result<()>
