MySql server status flags
Methods
impl StatusFlags
pub const SERVER_STATUS_IN_TRANS: StatusFlags
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.
pub const SERVER_STATUS_AUTOCOMMIT: StatusFlags
Server in auto_commit mode.
pub const SERVER_MORE_RESULTS_EXISTS: StatusFlags
Multi query - next query exists.
pub const SERVER_STATUS_NO_GOOD_INDEX_USED: StatusFlags
pub const SERVER_STATUS_NO_INDEX_USED: StatusFlags
pub const SERVER_STATUS_CURSOR_EXISTS: StatusFlags
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.
pub const SERVER_STATUS_LAST_ROW_SENT: StatusFlags
This flag is sent when a read-only cursor is exhausted, in reply to COM_STMT_FETCH command.
pub const SERVER_STATUS_DB_DROPPED: StatusFlags
A database was dropped.
pub const SERVER_STATUS_NO_BACKSLASH_ESCAPES: StatusFlags
pub const SERVER_STATUS_METADATA_CHANGED: StatusFlags
Sent to the client if after a prepared statement reprepare we discovered that the new statement returns a different number of result set columns.
pub const SERVER_QUERY_WAS_SLOW: StatusFlags
pub const SERVER_PS_OUT_PARAMS: StatusFlags
To mark ResultSet containing output parameter values.
pub const SERVER_STATUS_IN_TRANS_READONLY: StatusFlags
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.
pub const SERVER_SESSION_STATE_CHANGED: StatusFlags
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.
pub fn empty() -> StatusFlags
Returns an empty set of flags.
pub fn all() -> StatusFlags
Returns the set containing all flags.
pub fn bits(&self) -> u16
Returns the raw value of the flags currently stored.
pub fn from_bits(bits: u16) -> Option<StatusFlags>
Convert from underlying bit representation, unless that representation contains bits that do not correspond to a flag.
pub fn from_bits_truncate(bits: u16) -> StatusFlags
Convert from underlying bit representation, dropping any bits that do not correspond to flags.
pub fn is_empty(&self) -> bool
Returns true
if no flags are currently stored.
pub fn is_all(&self) -> bool
Returns true
if all flags are currently set.
pub fn intersects(&self, other: StatusFlags) -> bool
Returns true
if there are flags common to both self
and other
.
pub fn contains(&self, other: StatusFlags) -> bool
Returns true
all of the flags in other
are contained within self
.
pub fn insert(&mut self, other: StatusFlags)
Inserts the specified flags in-place.
pub fn remove(&mut self, other: StatusFlags)
Removes the specified flags in-place.
pub fn toggle(&mut self, other: StatusFlags)
Toggles the specified flags in-place.
pub fn set(&mut self, other: StatusFlags, value: bool)
Inserts or removes the specified flags depending on the passed value.
