Implementations

impl ServoRestyleDamage

pub const REPAINT: Self = _

Repaint the node itself.

Currently unused; need to decide how this propagates.

pub const REPOSITION: Self = _

The stacking-context-relative position of this node or its descendants has changed.

Propagates both up and down the flow tree.

pub const STORE_OVERFLOW: Self = _

Recompute the overflow regions (bounding box of object and all descendants).

Propagates down the flow tree because the computation is bottom-up.

pub const BUBBLE_ISIZES: Self = _

Recompute intrinsic inline_sizes (minimum and preferred).

Propagates down the flow tree because the computation is. bottom-up.

pub const REFLOW_OUT_OF_FLOW: Self = _

Recompute actual inline-sizes and block-sizes, only taking out-of-flow children into account.

Propagates up the flow tree because the computation is top-down.

pub const REFLOW: Self = _

Recompute actual inline_sizes and block_sizes.

Propagates up the flow tree because the computation is top-down.

pub const RESOLVE_GENERATED_CONTENT: Self = _

Re-resolve generated content.

Propagates up the flow tree because the computation is inorder.

pub const RECONSTRUCT_FLOW: Self = _

The entire flow needs to be reconstructed.

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) -> u8

Returns the raw value of the flags currently stored.

pub const fn from_bits(bits: u8) -> 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: u8) -> Self

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

pub const unsafe fn from_bits_unchecked(bits: u8) -> 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.

impl ServoRestyleDamage

pub fn compute_style_difference( old: &ComputedValues, new: &ComputedValues ) -> StyleDifference

Compute the StyleDifference (including the appropriate restyle damage) for a given style change between old and new.

pub fn rebuild_and_reflow() -> ServoRestyleDamage

Returns a bitmask that represents a flow that needs to be rebuilt and reflowed.

FIXME(bholley): Do we ever actually need this? Shouldn’t RECONSTRUCT_FLOW imply everything else?

pub fn reconstruct() -> ServoRestyleDamage

Returns a bitmask indicating that the frame needs to be reconstructed.

pub fn damage_for_parent( self, child_is_absolutely_positioned: bool ) -> ServoRestyleDamage

Supposing a flow has the given position property and this damage, returns the damage that we should add to the parent of this flow.

pub fn damage_for_child( self, parent_is_absolutely_positioned: bool, child_is_absolutely_positioned: bool ) -> ServoRestyleDamage

Supposing the parent of a flow with the given position property has this damage, returns the damage that we should add to this flow.
