impl FragmentFlags

pub const IS_BODY_ELEMENT_OF_HTML_ELEMENT_ROOT: Self = _

pub const IS_BR_ELEMENT: Self = _

Whether or not the node that created this Fragment is a   element.

pub const IS_FLEX_ITEM: Self = _

Whether or not this Fragment is a flex item.

pub const IS_REPLACED: Self = _

Whether or not this Fragment was created to contain a replaced element or is a replaced element.

pub const IS_TABLE_TH_OR_TD_ELEMENT: Self = _

Whether or not the node that created was a <table>, <th> or <td> element. Note that this does not include elements with display: table or display: table-cell.

pub const IS_OUTSIDE_LIST_ITEM_MARKER: Self = _

Whether or not this Fragment was created to contain a list item marker with a used value of list-style-position: outside.

pub const DO_NOT_PAINT: Self = _

Avoid painting the borders, backgrounds, and drop shadow for this fragment, this is used for empty table cells when ‘empty-cells’ is ‘hide’ and also table wrappers. This flag doesn’t avoid hit-testing nor does it prevent the painting outlines.

Convert from a bits value exactly.

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

The bitwise or (|) of the bits in two flags values.

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

The intersection of a source flags value with the complement of a target flags value (&!).

The bitwise exclusive-or (^) of the bits in two flags values.

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

Call insert when value is true or remove when value is false.

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

The bitwise or (|) of the bits in two flags values.

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

The intersection of a source flags value with the complement of a target flags value (&!).

This method is not equivalent to self & !other when other has unknown bits set. difference won’t truncate other, but the ! operator will.

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

The bitwise exclusive-or (^) of the bits in two flags values.

pub const fn complement(self) -> Self

The bitwise negation (!) of the bits in a flags value, truncating the result.

impl FragmentFlags

pub const fn iter(&self) -> Iter<FragmentFlags>

Yield a set of contained flags values.

Each yielded flags value will correspond to a defined named flag. Any unknown bits will be yielded together as a final flags value.

pub const fn iter_names(&self) -> IterNames<FragmentFlags>

Yield a set of contained named flags values.

This method is like iter, except only yields bits in contained named flags. Any unknown bits, or bits not corresponding to a contained flag will not be yielded.
