Provided methods

fn ping(self) -> BoxFuture<Self>

Returns future that resolves to Conn if COM_PING executed successfully.

fn disconnect(self) -> BoxFuture<()>

Returns future, that disconnects this connection from a server.

fn query<Q: AsRef<str>>(
    self,
    query: Q
) -> BoxFuture<QueryResult<Self, TextProtocol>>

Returns future that performs query.

fn first<Q, R>(self, query: Q) -> BoxFuture<(Self, Option<R>)> where
    Q: AsRef<str>,
    R: FromRow, 

Returns future that resolves to a first row of result of a query execution (if any).

Returned future will call R::from_row(row) internally.

fn drop_query<Q: AsRef<str>>(self, query: Q) -> BoxFuture<Self>

Returns future that performs query. Result will be dropped.

fn prepare<Q: AsRef<str>>(self, query: Q) -> BoxFuture<Stmt<Self>>

Returns future that prepares statement.

fn prep_exec<Q, P>(
    self,
    query: Q,
    params: P
) -> BoxFuture<QueryResult<Self, BinaryProtocol>> where
    Q: AsRef<str>,
    P: Into<Params>, 

Returns future that prepares and executes statement in one pass.

fn first_exec<Q, P, R>(
    self,
    query: Q,
    params: P
) -> BoxFuture<(Self, Option<R>)> where
    Q: AsRef<str>,
    P: Into<Params>,
    R: FromRow, 

Returns future that resolves to a first row of result of a statement execution (if any).

Returned future will call R::from_row(row) internally.

fn drop_exec<Q, P>(self, query: Q, params: P) -> BoxFuture<Self> where
    Q: AsRef<str>,
    P: Into<Params>, 

Returns future that prepares and executes statement. Result will be dropped.

fn batch_exec<Q, I, P>(self, query: Q, params_iter: I) -> BoxFuture<Self> where
    Q: AsRef<str>,
    I: IntoIterator<Item = P> + Send + 'static,
    I::IntoIter: Send + 'static,
    Params: From<P>,
    P: Send + 'static, 

Returns future that prepares statement and performs batch execution. Results will be dropped.

fn start_transaction(
    self,
    options: TransactionOptions
) -> BoxFuture<Transaction<Self>>

Returns future that starts transaction.
