pub enum Spacing<Value> {
    Normal,
    Value(Value),
}

normal

Value(Value)

<value>

Methods

impl<Value> Spacing<Value>

pub fn normal() -> Self

Returns normal.

pub fn parse_with<'i, 't, F>(
    context: &ParserContext,
    input: &mut Parser<'i, 't>,
    parse: F
) -> Result<Self, ParseError<'i>> where
    F: FnOnce(&ParserContext, &mut Parser<'i, 't>) -> Result<Value, ParseError<'i>>, 

Parses.

pub fn value(&self) -> Option<&Value>

Returns the spacing value, if not normal.

Trait Implementations

impl<Value: Clone> Clone for Spacing<Value>

fn clone(&self) -> Spacing<Value>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<Value: Copy> Copy for Spacing<Value>

impl<Value: Debug> Debug for Spacing<Value>

fn fmt(&self, __arg_0: &mut Formatter) -> Result

Formats the value using the given formatter.

impl<Value> MallocSizeOf for Spacing<Value> where
    Value: 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<Value: PartialEq> PartialEq for Spacing<Value>

fn eq(&self, __arg_0: &Spacing<Value>) -> bool

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

fn ne(&self, __arg_0: &Spacing<Value>) -> bool

This method tests for !=.

impl<Value> ToComputedValue for Spacing<Value> where
    Value: ToComputedValue, 

type ComputedValue = Spacing<<Value as ToComputedValue>::ComputedValue>

The computed value type we're going to be converted to.

fn to_computed_value(&self, context: &Context) -> Self::ComputedValue

Convert a specified value to a computed value, using itself and the data inside the Context.

fn from_computed_value(computed: &Self::ComputedValue) -> Self

Convert a computed value to specified value form.

impl<Value> ToCss for Spacing<Value> where
    Value: ToCss, 

fn to_css<W>(&self, dest: &mut W) -> Result where
    W: Write, 

Serialize self in CSS syntax, writing to dest.

fn to_css_string(&self) -> String

Serialize self in CSS syntax and return a string.

impl<Value> Animate for Spacing<Value> where
    Value: Animate + From<Au>, 

fn animate(&self, other: &Self, procedure: Procedure) -> Result<Self, ()>

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

impl<V> ComputeSquaredDistance for Spacing<V> where
    V: ComputeSquaredDistance + From<Au>, 

fn compute_squared_distance(&self, other: &Self) -> Result<SquaredDistance, ()>

Computes the squared distance between two animatable values.

impl<V> ToAnimatedZero for Spacing<V> where
    V: From<Au>, 

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.
