Methods

impl Number

pub fn new(val: CSSFloat) -> Self

Returns a new number with the value val.

pub fn get(&self) -> f32

Returns the numeric value, clamped if needed.

pub fn parse_non_negative<'i, 't>(
    context: &ParserContext,
    input: &mut Parser<'i, 't>
) -> Result<Number, ParseError<'i>>

pub fn parse_at_least_one<'i, 't>(
    context: &ParserContext,
    input: &mut Parser<'i, 't>
) -> Result<Number, ParseError<'i>>

pub fn clamp_to_one(self) -> Self

Clamp to 1.0 if the value is over 1.0.

Trait Implementations

impl Clone for Number

fn clone(&self) -> Number

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Copy for Number

impl Debug for Number

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

Formats the value using the given formatter.

impl MallocSizeOf for Number

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 Number

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

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

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

This method tests for !=.

impl PartialOrd for Number

fn partial_cmp(&self, __arg_0: &Number) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, __arg_0: &Number) -> bool

This method tests less than (for self and other) and is used by the < operator.

fn le(&self, __arg_0: &Number) -> bool

This method tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, __arg_0: &Number) -> bool

This method tests greater than (for self and other) and is used by the > operator.

fn ge(&self, __arg_0: &Number) -> bool

This method tests greater than or equal to (for self and other) and is used by the >= operator.

impl Parse for Number

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

Parse a value of this type.

impl ToComputedValue for Number

type ComputedValue = CSSFloat

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

fn to_computed_value(&self, _: &Context) -> CSSFloat

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

fn from_computed_value(computed: &CSSFloat) -> Self

Convert a computed value to specified value form.

impl ToCss for Number

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

impl From<Number> for f32

fn from(n: Number) -> Self

Performs the conversion.

impl From<Number> for f64

fn from(n: Number) -> Self

Performs the conversion.
