Methods

impl LengthOrPercentage

pub fn zero() -> LengthOrPercentage

pub fn one() -> LengthOrPercentage

1px length value for SVG defaults

pub fn is_definitely_zero(&self) -> bool

Returns true if the computed value is absolute 0 or 0%.

(Returns false for calc() values, even if ones that may resolve to zero.)

pub fn to_hash_key(&self) -> (Au, NotNaN<f32>)

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

Returns the used value.

pub fn to_pixel_length(&self, containing_length: Au) -> Length

Returns the used value as CSSPixelLength.

pub fn clamp_to_non_negative(self) -> Self

Returns the clamped non-negative values.

Trait Implementations

impl From<LengthOrPercentage> for CalcLengthOrPercentage

fn from(len: LengthOrPercentage) -> CalcLengthOrPercentage

Performs the conversion.

impl Animate for LengthOrPercentage

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

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

impl Clone for LengthOrPercentage

fn clone(&self) -> LengthOrPercentage

Returns a copy of the value.

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

Performs copy-assignment from source.

impl ComputeSquaredDistance for LengthOrPercentage

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

Computes the squared distance between two animatable values.

impl Copy for LengthOrPercentage

impl MallocSizeOf for LengthOrPercentage

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 PartialEq for LengthOrPercentage

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

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

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

This method tests for !=.

impl ToAnimatedZero for LengthOrPercentage

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.

impl ToCss for LengthOrPercentage

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 LengthOrPercentage

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

Formats the value using the given formatter.

impl From<Au> for LengthOrPercentage

fn from(length: Au) -> Self

Performs the conversion.

impl From<LengthOrPercentage> for NonNegativeLengthOrPercentage

fn from(lop: LengthOrPercentage) -> Self

Performs the conversion.

impl From<NonNegativeLengthOrPercentage> for LengthOrPercentage

fn from(lop: NonNegativeLengthOrPercentage) -> LengthOrPercentage

Performs the conversion.

impl ToAbsoluteLength for ComputedLengthOrPercentage

fn to_pixel_length(&self, containing_len: Option<Au>) -> Result<CSSFloat, ()>

Returns the absolute length as pixel value.

impl RepeatableListAnimatable for LengthOrPercentage

impl From<LengthOrPercentage> for NumberOrPercentage

fn from(lop: LengthOrPercentage) -> NumberOrPercentage

Performs the conversion.
