pub fn affected_rows(&self) -> u64

Returns the number of rows affected by the last INSERT, UPDATE, REPLACE or DELETE query.

pub async fn new<T: Into<Opts>>(opts: T) -> Result<Conn>

Returns future that resolves to Conn.

pub async fn from_url<T: AsRef<str>>(url: T) -> Result<Conn>

Returns future that resolves to Conn.

pub async fn reset(self) -> Result<Conn>

Returns future that resolves to a Conn with COM_RESET_CONNECTION executed on it.
