Enum layout_2020::taffy::stylo_taffy::convert::stylo::GenericSize

#[repr(C, u8)]
pub(crate) enum GenericSize<LengthPercent> {
    LengthPercentage(LengthPercent),
    Auto,
    MaxContent,
    MinContent,
    FitContent,
    Stretch,
    AnchorSizeFunction(Box<GenericAnchorSizeFunction<LengthPercent>>),
}

A generic value for the width, height, min-width, or min-height property.

Unlike max-width or max-height properties, a Size can be auto, and cannot be none.

Note that it only accepts non-negative values.

Animate a value towards another one, given an animation procedure.

impl<LengthPercent> Clone for GenericSize<LengthPercent>

where LengthPercent: Clone,

fn clone(&self) -> GenericSize<LengthPercent>

Returns a copy of the value.

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

Performs copy-assignment from source.

Computes the squared distance between two animatable values.

impl<LengthPercent> Debug for GenericSize<LengthPercent>

where LengthPercent: Debug,

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

Formats the value using the given formatter.

impl From<GenericSize<NonNegative<LengthPercentage>>> for Size<LengthPercentage>

fn from(size: StyleSize) -> Self

Converts to this type from the input type.

impl<LengthPercent> MallocSizeOf for GenericSize<LengthPercent>

where LengthPercent: 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 GenericSize<NonNegative<LengthPercentage>>

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

Parse a value of this type.

impl<LengthPercent> PartialEq for GenericSize<LengthPercent>

where LengthPercent: PartialEq,

fn eq(&self, other: &GenericSize<LengthPercent>) -> 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<LengthPercent> SpecifiedValueInfo for GenericSize<LengthPercent>

where LengthPercent: 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<LengthPercent> ToAnimatedValue for GenericSize<LengthPercent>

where LengthPercent: ToAnimatedValue,

where LengthPercent: ToAnimatedZero,

fn to_animated_zero(&self) -> Result<GenericSize<LengthPercent>, ()>

Returns a value that, when added with an underlying value, will produce the underlying value. This is used for SMIL animation’s “by-animation” where SMIL first interpolates from the zero value to the ‘by’ value, and then adds the result to the underlying value.

impl<LengthPercent> ToComputedValue for GenericSize<LengthPercent>

where LengthPercent: ToComputedValue,

type ComputedValue = GenericSize<<LengthPercent as ToComputedValue>::ComputedValue>
