Enum script_layout_interface::FragmentType

pub enum FragmentType {
    FragmentBody,
    BeforePseudoContent,
    AfterPseudoContent,
}

The type of fragment that a scroll root is created for.

This can only ever grow to maximum 4 entries. That’s because we cram the value of this enum into the lower 2 bits of the ScrollRootId, which otherwise contains a 32-bit-aligned heap address.

Variants

FragmentBody

A StackingContext for the fragment body itself.

BeforePseudoContent

A StackingContext created to contain ::before pseudo-element content.

AfterPseudoContent

A StackingContext created to contain ::after pseudo-element content.

Trait Implementations

impl Clone for FragmentType

fn clone(&self) -> FragmentType

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for FragmentType

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for FragmentType

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Hash for FragmentType

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl MallocSizeOf for FragmentType

fn size_of(&self, ops: &mut MallocSizeOfOps) -> usize

Measure the heap usage of all descendant heap-allocated structures, but not the space taken up by the value itself.

impl PartialEq for FragmentType

fn eq(&self, other: &FragmentType) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for FragmentType

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
