Struct selectors::matching::ElementSelectorFlags [−][src]
pub struct ElementSelectorFlags { /* fields omitted */ }
Set of flags that are set on either the element or its parent (depending on the flag) if the element could potentially match a selector.
Implementations
impl ElementSelectorFlags
[src]
impl ElementSelectorFlags
[src]pub const HAS_SLOW_SELECTOR: ElementSelectorFlags
[src]
When a child is added or removed from the parent, all the children must be restyled, because they may match :nth-last-child, :last-of-type, :nth-last-of-type, or :only-of-type.
pub const HAS_SLOW_SELECTOR_LATER_SIBLINGS: ElementSelectorFlags
[src]
When a child is added or removed from the parent, any later children must be restyled, because they may match :nth-child, :first-of-type, or :nth-of-type.
pub const HAS_EDGE_CHILD_SELECTOR: ElementSelectorFlags
[src]
When a child is added or removed from the parent, the first and last children must be restyled, because they may match :first-child, :last-child, or :only-child.
pub const HAS_EMPTY_SELECTOR: ElementSelectorFlags
[src]
The element has an empty selector, so when a child is appended we might need to restyle the parent completely.
pub const fn empty() -> ElementSelectorFlags
[src]
Returns an empty set of flags
pub const fn all() -> ElementSelectorFlags
[src]
Returns the set containing all flags.
pub const fn bits(&self) -> usize
[src]
Returns the raw value of the flags currently stored.
pub fn from_bits(bits: usize) -> Option<ElementSelectorFlags>
[src]
Convert from underlying bit representation, unless that representation contains bits that do not correspond to a flag.
pub const fn from_bits_truncate(bits: usize) -> ElementSelectorFlags
[src]
Convert from underlying bit representation, dropping any bits that do not correspond to flags.
pub const unsafe fn from_bits_unchecked(bits: usize) -> ElementSelectorFlags
[src]
Convert from underlying bit representation, preserving all bits (even those not corresponding to a defined flag).
pub const fn is_empty(&self) -> bool
[src]
Returns true
if no flags are currently stored.
pub const fn is_all(&self) -> bool
[src]
Returns true
if all flags are currently set.
pub const fn intersects(&self, other: ElementSelectorFlags) -> bool
[src]
Returns true
if there are flags common to both self
and other
.
pub const fn contains(&self, other: ElementSelectorFlags) -> bool
[src]
Returns true
all of the flags in other
are contained within self
.
pub fn insert(&mut self, other: ElementSelectorFlags)
[src]
Inserts the specified flags in-place.
pub fn remove(&mut self, other: ElementSelectorFlags)
[src]
Removes the specified flags in-place.
pub fn toggle(&mut self, other: ElementSelectorFlags)
[src]
Toggles the specified flags in-place.
pub fn set(&mut self, other: ElementSelectorFlags, value: bool)
[src]
Inserts or removes the specified flags depending on the passed value.

[src]
impl ElementSelectorFlags
[src]pub fn for_self(self) -> ElementSelectorFlags
[src]
Returns the subset of flags that apply to the element.
pub fn for_parent(self) -> ElementSelectorFlags
[src]
Returns the subset of flags that apply to the parent.
