Implementations§
source§impl ShapeFlags
impl ShapeFlags
sourcepub const ROUND_POSITIONS: Self = _
pub const ROUND_POSITIONS: Self = _
Round glyph positions and widths to whole device units This option should be set if the target renderer can’t do subpixel positioning of glyphs

impl ShapeFlags
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 fn from_bits_retain(bits: u32) -> Self
pub const fn from_bits_retain(bits: u32) -> Self
Convert from underlying bit representation, preserving all bits (even those not corresponding to a defined flag).
sourcepub fn from_name(name: &str) -> Option<Self>
pub fn from_name(name: &str) -> Option<Self>
Get the value for a flag from its stringified name.
Names are case-sensitive, so must correspond exactly to the identifier given to the flag.
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 insert(&mut self, other: Self)
pub fn insert(&mut self, other: Self)
Inserts the specified flags in-place.
This method is equivalent to union
.
sourcepub fn remove(&mut self, other: Self)
pub fn remove(&mut self, other: Self)
Removes the specified flags in-place.
This method is equivalent to difference
.
sourcepub fn toggle(&mut self, other: Self)
pub fn toggle(&mut self, other: Self)
Toggles the specified flags in-place.
This method is equivalent to symmetric_difference
.
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
.
Calculating self
bitwise and (&
) other, including
any bits that don’t correspond to a defined flag.
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
.
Calculates self
bitwise or (|
) other
, including
any bits that don’t correspond to a defined flag.
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
.
Calculates self
bitwise and (&!
) the bitwise negation of other
,
including any bits that don’t correspond to a defined flag.
This method is not equivalent to a & !b
when there are bits set that
don’t correspond to a defined flag. The !
operator will unset any
bits that don’t correspond to a flag, so they’ll always be unset by a &! b
,
but respected by a.difference(b)
.
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
.
Calculates self
bitwise exclusive or (^
) other
,
including any bits that don’t correspond to a defined flag.
sourcepub const fn complement(self) -> Self
pub const fn complement(self) -> Self
Returns the complement of this set of flags.
Calculates the bitwise negation (!
) of self
,
unsetting any bits that don’t correspond to a defined flag.
source§impl ShapeFlags
impl ShapeFlags
sourcepub const fn iter(&self) -> Iter<ShapeFlags>
pub const fn iter(&self) -> Iter<ShapeFlags>
Iterate over enabled flag values.
sourcepub const fn iter_names(&self) -> IterNames<ShapeFlags>
pub const fn iter_names(&self) -> IterNames<ShapeFlags>
Iterate over enabled flag values with their stringified names.
