Enum layout_2020::taffy::stylo_taffy::convert::stylo::GenericInset

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

Inset defined by the anchor element.

AnchorSizeFunction(Box<GenericAnchorSizeFunction<LP>>)

Inset defined by the size of the anchor element.

Computes the squared distance between two animatable values.

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

where P: Debug, LP: Debug,

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

Formats the value using the given formatter.

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 Parse for GenericInset<Percentage, LengthPercentage>

fn parse<'i, 't>( context: &ParserContext<'_>, input: &mut Parser<'i, 't>, ) -> Result<GenericInset<Percentage, LengthPercentage>, ParseError<'i, StyleParseErrorKind<'i>>>

Parse a value of this type.

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

where P: PartialEq, LP: PartialEq,

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

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

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

where LP: SpecifiedValueInfo,

fn collect_completion_keywords(f: &mut dyn FnMut(&[&'static str]))

Collect value starting words for the given specified value type. This includes keyword and function names which can appear at the beginning of a value of this type.

const SUPPORTED_TYPES: u8 = 0u8

Supported CssTypes by the given value type.

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

where P: ToAnimatedValue, LP: ToAnimatedValue,
