Struct style::values::computed::angle::Angle

#[repr(C)]
pub struct Angle(CSSFloat);

A computed angle in degrees.

Tuple Fields

0: CSSFloat

Implementations

impl Angle

pub fn from_radians(radians: CSSFloat) -> Self

Creates a computed Angle value from a radian amount.

pub fn from_degrees(degrees: CSSFloat) -> Self

Creates a computed Angle value from a degrees amount.

pub fn radians(&self) -> CSSFloat

Returns the amount of radians this angle represents.

pub fn radians64(&self) -> f64

Returns the amount of radians this angle represents as a f64.

Gecko stores angles as singles, but does this computation using doubles.

This is significant enough to mess up rounding to the nearest quarter-turn for 225 degrees, for example.

pub fn degrees(&self) -> CSSFloat

Return the value in degrees.

Trait Implementations

impl Add for Angle

type Output = Angle

The resulting type after applying the + operator.

fn add(self, rhs: Angle) -> Angle

Performs the + operation.

impl Animate for Angle

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

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

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 ComputeSquaredDistance for Angle

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

Computes the squared distance between two animatable values.

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 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 PartialOrd for Angle

fn partial_cmp(&self, other: &Angle) -> Option<Ordering>

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

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

Tests less than (for self and other) and is used by the < operator.

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

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

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

Tests greater than (for self and other) and is used by the > operator.

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

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

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 ToAnimatedValue for Angle

type AnimatedValue = Angle

The type of the animated value.

fn to_animated_value(self, _: &Context<'_>) -> Self

Converts this value to an animated value.

fn from_animated_value(animated: Self::AnimatedValue) -> Self

Converts back an animated value into a computed value.

impl ToAnimatedZero for Angle

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 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 ToResolvedValue for Angle

where CSSFloat: ToResolvedValue<ResolvedValue = CSSFloat>,

type ResolvedValue = Angle

The resolved value type we’re going to be converted to.

fn from_resolved_value(from: Self::ResolvedValue) -> Self

Convert a resolved value to resolved value form.

fn to_resolved_value(self, context: &Context<'_>) -> Self::ResolvedValue

Convert a resolved value to a resolved value.

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
