Struct selectors::matching::StyleRelations
[−]
pub struct StyleRelations { // some fields omitted }
Set of flags that determine the different kind of elements affected by the selector matching process.
This is used to implement efficient sharing.
Methods
impl StyleRelations
fn empty() -> StyleRelations
Returns an empty set of flags.
fn all() -> StyleRelations
Returns the set containing all flags.
fn bits(&self) -> u16
Returns the raw value of the flags currently stored.
fn from_bits(bits: u16) -> Option<StyleRelations>
Convert from underlying bit representation, unless that representation contains bits that do not correspond to a flag.
fn from_bits_truncate(bits: u16) -> StyleRelations
Convert from underlying bit representation, dropping any bits that do not correspond to flags.
fn is_empty(&self) -> bool
Returns true
if no flags are currently stored.
fn is_all(&self) -> bool
Returns true
if all flags are currently set.
fn intersects(&self, other: StyleRelations) -> bool
Returns true
if there are flags common to both self
and other
.
fn contains(&self, other: StyleRelations) -> bool
Returns true
all of the flags in other
are contained within self
.
fn insert(&mut self, other: StyleRelations)
Inserts the specified flags in-place.
fn remove(&mut self, other: StyleRelations)
Removes the specified flags in-place.
fn toggle(&mut self, other: StyleRelations)
Toggles the specified flags in-place.
