Enum GenericInset

#[repr(C)]
pub enum GenericInset<P, LP> {
    LengthPercentage(LP),
    Auto,
    AnchorFunction(Box<GenericAnchorFunction<P, Self>>),
    AnchorSizeFunction(Box<GenericAnchorSizeFunction<Self>>),
    AnchorContainingCalcFunction(LP),
}

Specified type for inset properties, which allows the use of the anchor() function. Note(dshin): LengthPercentageOrAuto is not used here because having LengthPercentageOrAuto and AnchorFunction in the enum pays the price of the discriminator for LengthPercentage | Auto as well as LengthPercentageOrAuto | AnchorFunction. This increases the size of the style struct, which would not be great. On the other hand, we trade for code duplication, so… :(

Variants

LengthPercentage(LP)

A <length-percentage> value.

Auto

An auto value.

AnchorFunction(Box<GenericAnchorFunction<P, Self>>)

Inset defined by the anchor element.

https://drafts.csswg.org/css-anchor-position-1/#anchor-pos

AnchorSizeFunction(Box<GenericAnchorSizeFunction<Self>>)

Inset defined by the size of the anchor element.

https://drafts.csswg.org/css-anchor-position-1/#anchor-pos

AnchorContainingCalcFunction(LP)

A <length-percentage> value, guaranteed to contain calc(), which then is guaranteed to contain anchor() or anchor-size().

impl<P, LP> MallocSizeOf for GenericInset<P, LP>

where P: MallocSizeOf, LP: MallocSizeOf,

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<P: PartialEq, LP: PartialEq> PartialEq for GenericInset<P, LP>

fn eq(&self, other: &GenericInset<P, LP>) -> bool

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

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