Methods

impl LengthOrPercentageOrNone

pub fn to_used_value(&self, containing_length: Au) -> Option<Au>

Returns the used value.

Trait Implementations

impl From<LengthOrPercentageOrNone> for Option<CalcLengthOrPercentage>

fn from(len: LengthOrPercentageOrNone) -> Option<CalcLengthOrPercentage>

Performs the conversion.

impl MallocSizeOf for LengthOrPercentageOrNone

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 Animate for LengthOrPercentageOrNone

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

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

impl Clone for LengthOrPercentageOrNone

fn clone(&self) -> LengthOrPercentageOrNone

Returns a copy of the value.

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

Performs copy-assignment from source.

impl ComputeSquaredDistance for LengthOrPercentageOrNone

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

Computes the squared distance between two animatable values.

impl Copy for LengthOrPercentageOrNone

impl PartialEq for LengthOrPercentageOrNone

fn eq(&self, __arg_0: &LengthOrPercentageOrNone) -> bool

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

fn ne(&self, __arg_0: &LengthOrPercentageOrNone) -> bool

This method tests for !=.

impl ToCss for LengthOrPercentageOrNone

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 Debug for LengthOrPercentageOrNone

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

Formats the value using the given formatter.

impl ToAnimatedZero for LengthOrPercentageOrNone

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.
