Flags for buffers.
Implementations§
source§impl BufferFlags
impl BufferFlags
sourcepub const BEGINNING_OF_TEXT: BufferFlags = _
pub const BEGINNING_OF_TEXT: BufferFlags = _
Indicates that special handling of the beginning of text paragraph can be applied to this buffer. Should usually be set, unless you are passing to the buffer only part of the text without the full context.
sourcepub const END_OF_TEXT: BufferFlags = _
pub const END_OF_TEXT: BufferFlags = _
Indicates that special handling of the end of text paragraph can be applied to this buffer, similar to BufferFlags::BEGINNING_OF_TEXT
.
sourcepub const PRESERVE_DEFAULT_IGNORABLES: BufferFlags = _
pub const PRESERVE_DEFAULT_IGNORABLES: BufferFlags = _
Indicates that characters with Default_Ignorable
Unicode property should use the corresponding glyph from the font, instead of hiding them (done by replacing them with the space glyph and zeroing the advance width.) This flag takes precedence over BufferFlags::REMOVE_DEFAULT_IGNORABLES
.
sourcepub const REMOVE_DEFAULT_IGNORABLES: BufferFlags = _
pub const REMOVE_DEFAULT_IGNORABLES: BufferFlags = _
Indicates that characters with Default_Ignorable
Unicode property should be removed from glyph string instead of hiding them (done by replacing them with the space glyph and zeroing the advance width.) BufferFlags::PRESERVE_DEFAULT_IGNORABLES
takes precedence over this flag.
sourcepub const DO_NOT_INSERT_DOTTED_CIRCLE: BufferFlags = _
pub const DO_NOT_INSERT_DOTTED_CIRCLE: BufferFlags = _
Indicates that a dotted circle should not be inserted in the rendering of incorrect character sequences (such as <0905 093E>
).
sourcepub const VERIFY: BufferFlags = _
pub const VERIFY: BufferFlags = _
Indicates that the shape() call and its variants should perform various verification processes on the results of the shaping operation on the buffer. If the verification fails, then either a buffer message is sent, if a message handler is installed on the buffer, or a message is written to standard error. In either case, the shaping result might be modified to show the failed output.
sourcepub const PRODUCE_UNSAFE_TO_CONCAT: BufferFlags = _
pub const PRODUCE_UNSAFE_TO_CONCAT: BufferFlags = _
Indicates that the UNSAFE_TO_CONCAT
glyph-flag should be produced by the shaper. By default it will not be produced since it incurs a cost.
source§impl BufferFlags
impl BufferFlags

The returned value is exactly the bits set in this flags value.
sourcepub const fn from_bits(bits: u32) -> Option<BufferFlags>
pub const fn from_bits(bits: u32) -> Option<BufferFlags>
Convert from a bits value.
This method will return None
if any unknown bits are set.

This method will return None
if name
is empty or doesn’t
correspond to any named flag.
sourcepub const fn intersects(&self, other: BufferFlags) -> bool
pub const fn intersects(&self, other: BufferFlags) -> bool
Whether any set bits in a source flags value are also set in a target flags value.
sourcepub const fn contains(&self, other: BufferFlags) -> bool

pub fn insert(&mut self, other: BufferFlags)
The bitwise or (|
) of the bits in two flags values.
sourcepub fn remove(&mut self, other: BufferFlags)
pub fn remove(&mut self, other: BufferFlags)
The intersection of a source flags value with the complement of a target flags value (&!
).
This method is not equivalent to self & !other

has unknown bits set.
remove
won’t truncate other
, but the !
operator will.
sourcepub fn toggle(&mut self, other: BufferFlags)
pub fn toggle(&mut self, other: BufferFlags)
The bitwise exclusive-or (^
) of the bits in two flags values.
sourcepub fn set(&mut self, other: BufferFlags, value: bool)
pub fn set(&mut self, other: BufferFlags, value: bool)
Call insert
when value
is true
or remove
when value
is false
.
sourcepub const fn intersection(self, other: BufferFlags) -> BufferFlags
pub const fn intersection(self, other: BufferFlags) -> BufferFlags
The bitwise and (&
) of the bits in two flags values.
sourcepub const fn union(self, other: BufferFlags) -> BufferFlags
pub const fn union(self, other: BufferFlags) -> BufferFlags
The bitwise or (|
) of the bits in two flags values.
sourcepub const fn difference(self, other: BufferFlags) -> BufferFlags
pub const fn difference(self, other: BufferFlags) -> BufferFlags
The intersection of a source flags value with the complement of a target flags value (&!
).
This method is not equivalent to self & !other
when other
has unknown bits set.
difference
won’t truncate other
, but the !
operator will.
sourcepub const fn symmetric_difference(self, other: BufferFlags) -> BufferFlags
pub const fn symmetric_difference(self, other: BufferFlags) -> BufferFlags
The bitwise exclusive-or (^
) of the bits in two flags values.
sourcepub const fn complement(self) -> BufferFlags
pub const fn complement(self) -> BufferFlags
The bitwise negation (!
) of the bits in a flags value, truncating the result.
source§impl BufferFlags
impl BufferFlags
sourcepub const fn iter(&self) -> Iter<BufferFlags>
pub const fn iter(&self) -> Iter<BufferFlags>
Yield a set of contained flags values.
Each yielded flags value will correspond to a defined named flag. Any unknown bits will be yielded together as a final flags value.
sourcepub const fn iter_names(&self) -> IterNames<BufferFlags>
pub const fn iter_names(&self) -> IterNames<BufferFlags>
Yield a set of contained named flags values.
This method is like iter
, except only yields bits in contained named flags.
Any unknown bits, or bits not corresponding to a contained flag will not be yielded.
