fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<Pos> MallocSizeOf for GenericPositionOrAuto<Pos>where Pos: 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<Pos> Parse for GenericPositionOrAuto<Pos>where Pos: Parse,

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

Parse a value of this type.

impl<Pos: PartialEq> PartialEq<GenericPositionOrAuto<Pos>> for GenericPositionOrAuto<Pos>

fn eq(&self, other: &GenericPositionOrAuto<Pos>) -> bool

This method tests for self and other values to be equal, and is used by ==.

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

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

impl<Pos> Serialize for GenericPositionOrAuto<Pos>where Pos: Serialize,

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

Serialize this value into the given Serde serializer.

const SUPPORTED_TYPES: u8 = _

Supported CssTypes by the given value type.

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.

impl<Pos> ToAnimatedZero for GenericPositionOrAuto<Pos>where Pos: ToAnimatedZero,

fn to_animated_zero(&self) -> Result<Self, ()>

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.
