Expand description
Represents something queryable like connection or transaction.
Provided Methods§
sourcefn ping(self) -> BoxFuture<Self>
fn ping(self) -> BoxFuture<Self>
Returns future that resolves to Conn
if COM_PING
executed successfully.
sourcefn disconnect(self) -> BoxFuture<()>
fn disconnect(self) -> BoxFuture<()>
Returns future that disconnects this connection from a server.
sourcefn query<Q: AsRef<str>>(
self,
query: Q
) -> BoxFuture<QueryResult<Self, TextProtocol>>
fn query<Q: AsRef<str>>(
self,
query: Q
) -> BoxFuture<QueryResult<Self, TextProtocol>>
Returns future that performs query
.
sourcefn first<Q, R>(self, query: Q) -> BoxFuture<(Self, Option<R>)>where
Q: AsRef<str>,
R: FromRow,
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.
sourcefn drop_query<Q: AsRef<str>>(self, query: Q) -> BoxFuture<Self>
fn drop_query<Q: AsRef<str>>(self, query: Q) -> BoxFuture<Self>
Returns future that performs query. Result will be dropped.
sourcefn prepare<Q: AsRef<str>>(self, query: Q) -> BoxFuture<Stmt<Self>>
fn prepare<Q: AsRef<str>>(self, query: Q) -> BoxFuture<Stmt<Self>>
Returns future that prepares statement.
sourcefn prep_exec<Q, P>(
self,
query: Q,
params: P
) -> BoxFuture<QueryResult<Self, BinaryProtocol>>where
Q: AsRef<str>,
P: Into<Params>,
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.
sourcefn first_exec<Q, P, R>(self, query: Q, params: P) -> BoxFuture<(Self, Option<R>)>where
Q: AsRef<str>,
P: Into<Params>,
R: FromRow,
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.
sourcefn drop_exec<Q, P>(self, query: Q, params: P) -> BoxFuture<Self>where
Q: AsRef<str>,
P: Into<Params>,
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.
sourcefn 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,
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.
sourcefn start_transaction(
self,
options: TransactionOptions
) -> BoxFuture<Transaction<Self>>
fn start_transaction(
self,
options: TransactionOptions
) -> BoxFuture<Transaction<Self>>
Returns future that starts transaction.
