Struct mysql_async::Conn [−][src]
pub struct Conn { /* fields omitted */ }
Expand description
MySql server connection.
Implementations
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.
Returns the number of rows affected by the last INSERT
, UPDATE
, REPLACE
or DELETE
query.
Text information, as reported by the server in the last OK packet, or an empty string.
Number of warnings, as reported by the server in the last OK packet, or 0
.
Returns a reference to the last OK packet.
Disconnects this connection from server.
Returns a future that resolves to Conn
.
Returns a future that resolves to Conn
.
Executes COM_RESET_CONNECTION
on self
.
If server version is older than 5.7.2, then it’ll reconnect.
Starts a transaction.
