Implementations§

Source§

impl StatusFlags

Source

pub const SERVER_STATUS_IN_TRANS: Self = _

Is raised when a multi-statement transaction has been started, either explicitly, by means of BEGIN or COMMIT AND CHAIN, or implicitly, by the first transactional statement, when autocommit=off.

Source

pub const SERVER_STATUS_AUTOCOMMIT: Self = _

Server in auto_commit mode.

Source

pub const SERVER_MORE_RESULTS_EXISTS: Self = _

Multi query - next query exists.

Source

pub const SERVER_STATUS_NO_GOOD_INDEX_USED: Self = _

Source

pub const SERVER_STATUS_NO_INDEX_USED: Self = _

Source

pub const SERVER_STATUS_CURSOR_EXISTS: Self = _

The server was able to fulfill the clients request and opened a read-only non-scrollable cursor for a query. This flag comes in reply to COM_STMT_EXECUTE and COM_STMT_FETCH commands. Used by Binary Protocol Resultset to signal that COM_STMT_FETCH must be used to fetch the row-data.

Source

pub const SERVER_STATUS_LAST_ROW_SENT: Self = _

This flag is sent when a read-only cursor is exhausted, in reply to COM_STMT_FETCH command.

Source

pub const SERVER_STATUS_DB_DROPPED: Self = _

A database was dropped.

Source

pub const SERVER_STATUS_NO_BACKSLASH_ESCAPES: Self = _

Source

pub const SERVER_STATUS_METADATA_CHANGED: Self = _

Sent to the client if after a prepared statement reprepare we discovered that the new statement returns a different number of result set columns.

Source

pub const SERVER_QUERY_WAS_SLOW: Self = _

Source

pub const SERVER_PS_OUT_PARAMS: Self = _

To mark ResultSet containing output parameter values.

Source

pub const SERVER_STATUS_IN_TRANS_READONLY: Self = _

Set at the same time as SERVER_STATUS_IN_TRANS if the started multi-statement transaction is a read-only transaction. Cleared when the transaction commits or aborts. Since this flag is sent to clients in OK and EOF packets, the flag indicates the transaction status at the end of command execution.

Source

pub const SERVER_SESSION_STATE_CHANGED: Self = _

This status flag, when on, implies that one of the state information has changed on the server because of the execution of the last statement.

Source

pub const SERVER_STATUS_ANSI_QUOTES: Self = _

Introduced by mariadb. Contain the information about ANSI_QUOTES SQL_MODE.

Yield a set of contained named flags values.

This method is like iter, except only yields bits in contained named flags. Any unknown bits, or bits not corresponding to a contained flag will not be yielded.
