[−][src]Struct mysql_async::Conn
Methods
impl Conn
[src]
pub fn last_insert_id(&self) -> Option<u64>
[src]
Returns the ID generated by a query (usually INSERT
) on a table with a column having the
AUTO_INCREMENT
attribute. Returns None
if there was no previous query on the connection
or if the query did not update an AUTO_INCREMENT value.
pub fn affected_rows(&self) -> u64
[src]
Returns the number of rows affected by the last INSERT
, UPDATE
, REPLACE
or DELETE
query.
pub fn new<T: Into<Opts>>(opts: T) -> impl MyFuture<Conn>
[src]
Returns future that resolves to Conn
.
pub fn from_url<T: AsRef<str>>(url: T) -> impl MyFuture<Conn>
[src]
Returns future that resolves to Conn
.
pub fn reset(self) -> impl MyFuture<Conn>
[src]
Returns future that resolves to a Conn
with COM_RESET_CONNECTION
executed on it.
