Implementations

impl RestyleHint

pub const RESTYLE_SELF: Self = _

Do a selector match of the element.

pub const RESTYLE_PSEUDOS: Self = _

Do a selector match of the element’s pseudo-elements. Always to be combined with RESTYLE_SELF.

pub const RESTYLE_SELF_IF_PSEUDO: Self = _

Do a selector match if the element is a pseudo-element.

pub const RESTYLE_DESCENDANTS: Self = _

Do a selector match of the element’s descendants.

pub const RECASCADE_SELF: Self = _

Recascade the current element.

pub const RECASCADE_SELF_IF_INHERIT_RESET_STYLE: Self = _

Recascade the current element if it inherits any reset style.

pub const RECASCADE_DESCENDANTS: Self = _

Recascade all descendant elements.

pub const RESTYLE_CSS_TRANSITIONS: Self = _

Replace the style data coming from CSS transitions without updating any other style data. This hint is only processed in animation-only traversal which is prior to normal traversal.

pub const RESTYLE_CSS_ANIMATIONS: Self = _

Replace the style data coming from CSS animations without updating any other style data. This hint is only processed in animation-only traversal which is prior to normal traversal.

pub const RESTYLE_STYLE_ATTRIBUTE: Self = _

Don’t re-run selector-matching on the element, only the style attribute has changed, and this change didn’t have any other dependencies.

pub const RESTYLE_SMIL: Self = _

Replace the style data coming from SMIL animations without updating any other style data. This hint is only processed in animation-only traversal which is prior to normal traversal.

pub const fn empty() -> Self

Returns an empty set of flags.

pub const fn all() -> Self

Returns the set containing all flags.

pub const fn bits(&self) -> u16

Returns the raw value of the flags currently stored.

pub const fn from_bits(bits: u16) -> Option<Self>

Convert from underlying bit representation, unless that representation contains bits that do not correspond to a flag.

pub const fn from_bits_truncate(bits: u16) -> Self

Convert from underlying bit representation, dropping any bits that do not correspond to flags.

pub const unsafe fn from_bits_unchecked(bits: u16) -> Self

Convert from underlying bit representation, preserving all bits (even those not corresponding to a defined flag).

Safety

The caller of the bitflags! macro can chose to allow or disallow extra bits for their bitflags type.

The caller of from_bits_unchecked() has to ensure that all bits correspond to a defined flag or that extra bits are valid for this bitflags type.

pub const fn is_empty(&self) -> bool

Returns true if no flags are currently stored.

pub const fn is_all(&self) -> bool

Returns true if all flags are currently set.

pub const fn intersects(&self, other: Self) -> bool

Returns true if there are flags common to both self and other.

pub const fn contains(&self, other: Self) -> bool

Returns true if all of the flags in other are contained within self.

pub fn insert(&mut self, other: Self)

Inserts the specified flags in-place.

pub fn remove(&mut self, other: Self)

Removes the specified flags in-place.

pub fn toggle(&mut self, other: Self)

Toggles the specified flags in-place.

pub fn set(&mut self, other: Self, value: bool)

Inserts or removes the specified flags depending on the passed value.

pub const fn intersection(self, other: Self) -> Self

Returns the intersection between the flags in self and other.

Specifically, the returned set contains only the flags which are present in both self and other.

This is equivalent to using the & operator (e.g. ops::BitAnd), as in flags & other.

pub const fn union(self, other: Self) -> Self

Returns the union of between the flags in self and other.

Specifically, the returned set contains all flags which are present in either self or other, including any which are present in both (see Self::symmetric_difference if that is undesirable).

This is equivalent to using the | operator (e.g. ops::BitOr), as in flags | other.

pub const fn difference(self, other: Self) -> Self

Returns the difference between the flags in self and other.

Specifically, the returned set contains all flags present in self, except for the ones present in other.

It is also conceptually equivalent to the “bit-clear” operation: flags & !other (and this syntax is also supported).

This is equivalent to using the - operator (e.g. ops::Sub), as in flags - other.

pub const fn symmetric_difference(self, other: Self) -> Self

Returns the symmetric difference between the flags in self and other.

Specifically, the returned set contains the flags present which are present in self or other, but that are not present in both. Equivalently, it contains the flags present in exactly one of the sets self and other.

This is equivalent to using the ^ operator (e.g. ops::BitXor), as in flags ^ other.

pub const fn complement(self) -> Self

Returns the complement of this set of flags.

Specifically, the returned set contains all the flags which are not set in self, but which are allowed for this type.

Alternatively, it can be thought of as the set difference between Self::all() and self (e.g. Self::all() - self)

This is equivalent to using the ! operator (e.g. ops::Not), as in !flags.

pub fn propagate(&mut self, traversal_flags: &TraversalFlags) -> Self

Propagates this restyle hint to a child element.

fn propagate_for_non_animation_restyle(&self) -> Self

Returns a new RestyleHint appropriate for children of the current element.

pub fn replacements() -> Self

Returns a hint that contains all the replacement hints.

pub fn for_animations() -> Self

The replacements for the animation cascade levels.

pub fn has_animation_hint(&self) -> bool

Returns whether the hint specifies that an animation cascade level must be replaced.

pub fn has_animation_hint_or_recascade(&self) -> bool

Returns whether the hint specifies that an animation cascade level must be replaced.

pub fn has_non_animation_hint(&self) -> bool

Returns whether the hint specifies some restyle work other than an animation cascade level replacement.

pub fn has_replacements(&self) -> bool

Returns whether the hint specifies that some cascade levels must be replaced.

pub fn remove_animation_hints(&mut self)

Removes all of the animation-related hints.
