Enum GenericSize

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

Implementations

impl<LengthPercentage> GenericSize<LengthPercentage>

pub fn auto() -> GenericSize<LengthPercentage>

auto value.

pub fn is_auto(&self) -> bool

Returns whether we’re the auto value.

impl GenericSize<NonNegative<LengthPercentage>>

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

Parses, with quirks.

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

Parse a size for width or height, where -webkit-fill-available support is only controlled by one pref (vs. other properties where there’s an additional pref check): TODO(dholbert) Remove this custom parse func in bug 1989073, along with ‘layout.css.webkit-fill-available.all-size-properties.enabled’.

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

Parse a size for width or height, where -webkit-fill-available support is only controlled by one pref (vs. other properties where there’s an additional pref check): TODO(dholbert) Remove this custom parse func in bug 1989073, along with ‘layout.css.webkit-fill-available.all-size-properties.enabled’.

pub fn zero_percent() -> GenericSize<NonNegative<LengthPercentage>>

Returns 0%.

Trait Implementations

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 duplicate of the value.

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

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>
