Struct style::data::ElementDataFlags []

pub struct ElementDataFlags { /* fields omitted */ }

Various flags stored on ElementData.

Methods

impl ElementDataFlags

WAS_RESTYLED: ElementDataFlags = ElementDataFlags{bits: 1 << 0,}

Whether the styles changed for this restyle.

TRAVERSED_WITHOUT_STYLING: ElementDataFlags = ElementDataFlags{bits: 1 << 1,}

Whether the last traversal of this element did not do any style computation. This is not true during the initial styling pass, nor is it true when we restyle (in which case WAS_RESTYLED is set).

This bit always corresponds to the last time the element was traversed, so each traversal simply updates it with the appropriate value.

PRIMARY_STYLE_REUSED_VIA_RULE_NODE: ElementDataFlags = ElementDataFlags{bits: 1 << 2,}

Whether the primary style of this element data was reused from another element via a rule node comparison. This allows us to differentiate between elements that shared styles because they met all the criteria of the style sharing cache, compared to elements that reused style structs via rule node identity.

The former gives us stronger transitive guarantees that allows us to apply the style sharing cache to cousins.

Returns an empty set of flags.

Returns the set containing all flags.

Returns the raw value of the flags currently stored.

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

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

Returns true if no flags are currently stored.

Returns true if all flags are currently set.

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

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

Inserts the specified flags in-place.

Removes the specified flags in-place.

Toggles the specified flags in-place.

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