Struct selectors::matching::ElementFlags
[−]
pub struct ElementFlags { // some fields omitted }
Set of flags that are set on the parent depending on whether a child could potentially match a selector.
These setters, in the case of Servo, must be atomic, due to the parallel traversal.
Methods
impl ElementFlags
fn empty() -> ElementFlags
Returns an empty set of flags.
fn all() -> ElementFlags
Returns the set containing all flags.
fn bits(&self) -> u8
Returns the raw value of the flags currently stored.
fn from_bits(bits: u8) -> Option<ElementFlags>
Convert from underlying bit representation, unless that representation contains bits that do not correspond to a flag.
fn from_bits_truncate(bits: u8) -> ElementFlags
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: ElementFlags) -> bool
Returns true
if there are flags common to both self
and other
.
fn contains(&self, other: ElementFlags) -> bool
Returns true
all of the flags in other
are contained within self
.
fn insert(&mut self, other: ElementFlags)
Inserts the specified flags in-place.
fn remove(&mut self, other: ElementFlags)
Removes the specified flags in-place.
fn toggle(&mut self, other: ElementFlags)
Toggles the specified flags in-place.
