Trait HostConnection

pub trait HostConnection: Sized + 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", so this trait is not object safe.

Implementations on Foreign Types

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

async fn open( &mut self, database: String, ) -> Result<Resource<Connection>, Error>

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.

async fn execute( &mut self, self_: Resource<Connection>, statement: String, parameters: Vec<Value>, ) -> Result<QueryResult, Error>

Execute a statement returning back data if there is any

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