sourcepub const fn empty() -> ColumnFlags
pub const fn empty() -> ColumnFlags
Returns an empty set of flags.
sourcepub const fn all() -> ColumnFlags
pub const fn all() -> ColumnFlags
Returns the set containing all flags.
sourcepub const fn from_bits(bits: u16) -> Option<ColumnFlags>

Convert from underlying bit representation, unless that representation contains bits that do not correspond to a flag.
sourcepub const fn from_bits_truncate(bits: u16) -> ColumnFlags
pub const fn from_bits_truncate(bits: u16) -> ColumnFlags

sourcepub const unsafe fn from_bits_unchecked(bits: u16) -> ColumnFlags
pub const unsafe fn from_bits_unchecked(bits: u16) -> ColumnFlags
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: ColumnFlags) -> bool
pub const fn intersects(&self, other: ColumnFlags) -> bool
Returns true
if there are flags common to both self
and other
.
sourcepub const fn contains(&self, other: ColumnFlags) -> bool
pub const fn contains(&self, other: ColumnFlags) -> bool
Returns true
if all of the flags in other
are contained within self
.
sourcepub fn insert(&mut self, other: ColumnFlags)
pub fn insert(&mut self, other: ColumnFlags)
Inserts the specified flags in-place.
sourcepub fn remove(&mut self, other: ColumnFlags)
pub fn remove(&mut self, other: ColumnFlags)
Removes the specified flags in-place.
sourcepub fn toggle(&mut self, other: ColumnFlags)
pub fn toggle(&mut self, other: ColumnFlags)
Toggles the specified flags in-place.
sourcepub fn set(&mut self, other: ColumnFlags, value: bool)
pub fn set(&mut self, other: ColumnFlags, value: bool)
Inserts or removes the specified flags depending on the passed value.
sourcepub const fn intersection(self, other: ColumnFlags) -> ColumnFlags
pub const fn intersection(self, other: ColumnFlags) -> ColumnFlags
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: ColumnFlags) -> ColumnFlags
pub const fn union(self, other: ColumnFlags) -> ColumnFlags
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: ColumnFlags) -> ColumnFlags
pub const fn difference(self, other: ColumnFlags) -> ColumnFlags
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: ColumnFlags) -> ColumnFlags
pub const fn symmetric_difference(self, other: ColumnFlags) -> ColumnFlags
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) -> ColumnFlags
pub const fn complement(self) -> ColumnFlags
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
.
