pub const CLIENT_CONNECT_ATTRS: Self = _
sourcepub const CLIENT_PLUGIN_AUTH_LENENC_CLIENT_DATA: Self = _
pub const CLIENT_PLUGIN_AUTH_LENENC_CLIENT_DATA: Self = _
Enable authentication response packet to be larger than 255 bytes. When the ability to change default plugin require that the initial password field in the Protocol::HandshakeResponse41 paclet can be of arbitrary size. However, the 4.1 client-server protocol limits the length of the auth-data-field sent from client to server to 255 bytes. The solution is to change the type of the field to a true length encoded string and indicate the protocol change with this client capability flag.
Server
Understands length-encoded integer for auth response data in Protocol::HandshakeResponse41.
Client
Length of auth response data in Protocol::HandshakeResponse41 is a length-encoded integer.
Note
The flag was introduced in 5.6.6, but had the wrong value.
sourcepub const CLIENT_CAN_HANDLE_EXPIRED_PASSWORDS: Self = _
pub const CLIENT_CAN_HANDLE_EXPIRED_PASSWORDS: Self = _
sourcepub const CLIENT_SESSION_TRACK: Self = _
pub const CLIENT_SESSION_TRACK: Self = _
Capable of handling server state change information. Its a hint to the server to include the state change information in OK_Packet.
Server
Can set SERVER_SESSION_STATE_CHANGED in the SERVER_STATUS_flags_enum and send Session State Information in a OK_Packet.
Client
Expects the server to send Session State Information in a OK_Packet.
sourcepub const CLIENT_DEPRECATE_EOF: Self = _
pub const CLIENT_DEPRECATE_EOF: Self = _
Client no longer needs EOF_Packet and will use OK_Packet instead.
Server
Can send OK after a Text Resultset.
Client
Expects an OK_Packet (instead of EOF_Packet) after the resultset rows of a Text Resultset.
Background
To support CLIENT_SESSION_TRACK, additional information must be sent after all successful commands. Although the OK_Packet is extensible, the EOF_Packet is not due to the overlap of its bytes with the content of the Text Resultset Row.
Therefore, the EOF_Packet in the Text Resultset is replaced with an OK_Packet. EOF_Packet is deprecated as of MySQL 5.7.5.
sourcepub const CLIENT_PROGRESS_OBSOLETE: Self = _
pub const CLIENT_PROGRESS_OBSOLETE: Self = _
Client or server supports progress reports within error packet.
sourcepub const CLIENT_SSL_VERIFY_SERVER_CERT: Self = _
pub const CLIENT_SSL_VERIFY_SERVER_CERT: Self = _
Verify server certificate. Client only flag.
Deprecated in favor of –ssl-mode.
sourcepub const CLIENT_REMEMBER_OPTIONS: Self = _
pub const CLIENT_REMEMBER_OPTIONS: Self = _
Don’t reset the options after an unsuccessful connect. Client only flag.
sourcepub const fn from_bits(bits: u32) -> Option<Self>
pub const fn from_bits(bits: u32) -> Option<Self>
Convert from underlying bit representation, unless that representation contains bits that do not correspond to a flag.
sourcepub const fn from_bits_truncate(bits: u32) -> Self
pub const fn from_bits_truncate(bits: u32) -> Self
Convert from underlying bit representation, dropping any bits that do not correspond to flags.
sourcepub const unsafe fn from_bits_unchecked(bits: u32) -> Self
pub const unsafe fn from_bits_unchecked(bits: u32) -> Self
Convert from underlying bit representation, preserving all bits (even those not corresponding to a defined flag).
Safety
The caller of the bitflags!
macro can chose to allow or
disallow extra bits for their bitflags type.
The caller of from_bits_unchecked()
has to ensure that
all bits correspond to a defined flag or that extra bits
are valid for this bitflags type.
sourcepub const fn intersects(&self, other: Self) -> bool
pub const fn intersects(&self, other: Self) -> bool
Returns true
if there are flags common to both self
and other
.
sourcepub const fn contains(&self, other: Self) -> bool
pub const fn contains(&self, other: Self) -> bool
Returns true
if all of the flags in other
are contained within self
.
sourcepub fn set(&mut self, other: Self, value: bool)
pub fn set(&mut self, other: Self, value: bool)
Inserts or removes the specified flags depending on the passed value.
sourcepub const fn intersection(self, other: Self) -> Self
pub const fn intersection(self, other: Self) -> Self
Returns the intersection between the flags in self
and
other
.
Specifically, the returned set contains only the flags which are
present in both self
and other
.
This is equivalent to using the &
operator (e.g.
ops::BitAnd
), as in flags & other
.
sourcepub const fn union(self, other: Self) -> Self
pub const fn union(self, other: Self) -> Self
Returns the union of between the flags in self
and other
.
Specifically, the returned set contains all flags which are
present in either self
or other
, including any which are
present in both (see Self::symmetric_difference
if that
is undesirable).
This is equivalent to using the |
operator (e.g.
ops::BitOr
), as in flags | other
.
sourcepub const fn difference(self, other: Self) -> Self
pub const fn difference(self, other: Self) -> Self
Returns the difference between the flags in self
and other
.
Specifically, the returned set contains all flags present in
self
, except for the ones present in other
.
It is also conceptually equivalent to the “bit-clear” operation:
flags & !other
(and this syntax is also supported).
This is equivalent to using the -
operator (e.g.
ops::Sub
), as in flags - other
.
sourcepub const fn symmetric_difference(self, other: Self) -> Self
pub const fn symmetric_difference(self, other: Self) -> Self
Returns the symmetric difference between the flags
in self
and other
.
Specifically, the returned set contains the flags present which
are present in self
or other
, but that are not present in
both. Equivalently, it contains the flags present in exactly
one of the sets self
and other
.
This is equivalent to using the ^
operator (e.g.
ops::BitXor
), as in flags ^ other
.
sourcepub const fn complement(self) -> Self
pub const fn complement(self) -> Self
Returns the complement of this set of flags.
Specifically, the returned set contains all the flags which are
not set in self
, but which are allowed for this type.
Alternatively, it can be thought of as the set difference
between Self::all()
and self
(e.g. Self::all() - self
)
This is equivalent to using the !
operator (e.g.
ops::Not
), as in !flags
.
