Implementations
sourceimpl GtidFlags
impl GtidFlags
sourcepub const MAY_HAVE_SBR: GtidFlags = Self{ bits: 1,}
pub const MAY_HAVE_SBR: GtidFlags = Self{ bits: 1,}
Transaction may have changes logged with SBR.
In 5.6, 5.7.0-5.7.18, and 8.0.0-8.0.1, this flag is always set. Starting in 5.7.19 and 8.0.2, this flag is cleared if the transaction only contains row events. It is set if any part of the transaction is written in statement format.
sourcepub const fn from_bits(bits: u8) -> Option<GtidFlags>
pub const fn from_bits(bits: u8) -> Option<GtidFlags>
Convert from underlying bit representation, unless that representation contains bits that do not correspond to a flag.
sourcepub const fn from_bits_truncate(bits: u8) -> GtidFlags
pub const fn from_bits_truncate(bits: u8) -> GtidFlags
Convert from underlying bit representation, dropping any bits that do not correspond to flags.
sourcepub const unsafe fn from_bits_unchecked(bits: u8) -> GtidFlags
pub const unsafe fn from_bits_unchecked(bits: u8) -> GtidFlags
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: GtidFlags) -> bool
pub const fn intersects(&self, other: GtidFlags) -> bool
Returns true
if there are flags common to both self
and other
.
sourcepub const fn contains(&self, other: GtidFlags) -> bool
pub const fn contains(&self, other: GtidFlags) -> bool
Returns true
if all of the flags in other
are contained within self
.
sourcepub fn set(&mut self, other: GtidFlags, value: bool)
pub fn set(&mut self, other: GtidFlags, value: bool)
Inserts or removes the specified flags depending on the passed value.
sourcepub const fn intersection(self, other: GtidFlags) -> GtidFlags
pub const fn intersection(self, other: GtidFlags) -> GtidFlags
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: GtidFlags) -> GtidFlags
pub const fn union(self, other: GtidFlags) -> GtidFlags
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: GtidFlags) -> GtidFlags
pub const fn difference(self, other: GtidFlags) -> GtidFlags
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: GtidFlags) -> GtidFlags
pub const fn symmetric_difference(self, other: GtidFlags) -> GtidFlags
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) -> GtidFlags
pub const fn complement(self) -> GtidFlags
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
.
