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

pub struct Angle {
    value: AngleDimension,
    was_calc: bool,
}

A specified Angle value, which is just the angle dimension, plus whether it was specified as calc() or not.

Fields

value: AngleDimension

was_calc: bool

Implementations

impl Angle

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

Creates an angle with the given value in degrees.

pub fn from_radians(value: CSSFloat) -> Self

Creates an angle with the given value in radians.

pub fn zero() -> Self

Return 0deg.

pub fn degrees(&self) -> CSSFloat

Returns the value of the angle in degrees, mostly for calc().

pub fn radians(&self) -> CSSFloat

Returns the value of the angle in radians.

pub fn was_calc(&self) -> bool

Whether this specified angle came from a calc() expression.

pub fn from_calc(degrees: CSSFloat) -> Self

Returns an Angle parsed from a calc() expression.

pub fn unit(&self) -> &'static str

Returns the unit of the angle.

impl Angle

pub fn parse_dimension( value: CSSFloat, unit: &str, was_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.

pub(super) fn parse_internal<'i, 't>( context: &ParserContext<'_>, input: &mut Parser<'i, 't>, allow_unitless_zero: AllowUnitlessZeroAngle, ) -> Result<Self, ParseError<'i>>

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 Debug for Angle

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Angle

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

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 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.

impl PartialEq for Angle

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

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for Angle

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl SpecifiedValueInfo for Angle

const SUPPORTED_TYPES: u8 = 0u8

Supported CssTypes by the given value type.

fn collect_completion_keywords(_f: &mut dyn FnMut(&[&'static str]))

Collect value starting words for the given specified value type. This includes keyword and function names which can appear at the beginning of a value of this type.

impl ToComputedValue for Angle

type ComputedValue = Angle

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 ToCss for Angle

fn to_css<W>(&self, dest: &mut CssWriter<'_, 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 ToRadians for Angle

fn radians64(&self) -> f64

Return the radians value as a 64-bit floating point value.

impl ToShmem for Angle

fn to_shmem(&self, builder: &mut SharedMemoryBuilder) -> Result<Self>

Clones this value into a form suitable for writing into a SharedMemoryBuilder.

impl Zero for Angle

fn zero() -> Self

Returns the zero value.

fn is_zero(&self) -> bool

Returns whether this value is zero.

impl Copy for Angle

impl StructuralPartialEq for Angle
