Struct style::values::specified::angle::Angle

pub struct Angle { /* fields omitted */ }

A specified angle.

Computed angles are essentially same as specified ones except for calc() value serialization. Therefore we are storing a computed angle inside to hold the actual value and its unit.

Methods

impl Angle

pub fn from_degrees(value: CSSFloat, was_calc: bool) -> Self

Creates an angle with the given value in degrees.

pub fn from_gradians(value: CSSFloat, was_calc: bool) -> Self

Creates an angle with the given value in gradians.

pub fn from_turns(value: CSSFloat, was_calc: bool) -> Self

Creates an angle with the given value in turns.

pub fn from_radians(value: CSSFloat, was_calc: bool) -> Self

Creates an angle with the given value in radians.

pub fn radians(self) -> f32

Returns the amount of radians this angle represents.

pub fn degrees(self) -> f32

Returns the amount of degrees this angle represents.

pub fn zero() -> Self

Returns 0deg.

pub fn from_calc(radians: CSSFloat) -> Self

Returns an Angle parsed from a calc() expression.

impl Angle

pub fn parse_dimension(
    value: CSSFloat,
    unit: &str,
    from_calc: bool
) -> Result<Angle, ()>

Parse an <angle> value given a value and an unit.

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

Parse an <angle> allowing unitless zero to represent a zero angle.

See the comment in AllowUnitlessZeroAngle for why.

Trait Implementations

impl Clone for Angle

fn clone(&self) -> Angle

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Copy for Angle

impl Debug for Angle

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

Formats the value using the given formatter.

impl MallocSizeOf for Angle

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 Angle

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

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

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

This method tests for !=.

impl ToCss for Angle

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 ToComputedValue for Angle

type ComputedValue = ComputedAngle

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 AsRef<ComputedAngle> for Angle

fn as_ref(&self) -> &ComputedAngle

Performs the conversion.

impl Parse for Angle

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

Parses an angle according to CSS-VALUES § 6.1.
