Enum SuperellipseArg 

pub enum SuperellipseArg {
    Number(Number),
    Infinity,
    NegativeInfinity,
}

The argument to the superellipse() function.

superellipse(K) defines the corner shape using the unit equation x^(2^K) + y^(2^K) = 1. infinity and -infinity are accepted as special-cased keyword arguments.

Variants

Number(Number)

<number> argument.

Infinity

The infinity keyword.

NegativeInfinity

The -infinity keyword (lexed as the literal text -infinity).

Implementations

impl SuperellipseArg

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

pub fn to_k(&self, context: &Context<'_>) -> f32

Resolve to a numeric K value (possibly +/- infinity).

Trait Implementations

impl Clone for SuperellipseArg

fn clone(&self) -> SuperellipseArg

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SuperellipseArg

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

Formats the value using the given formatter.

impl MallocSizeOf for SuperellipseArg

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 SuperellipseArg

fn eq(&self, other: &SuperellipseArg) -> 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 SpecifiedValueInfo for SuperellipseArg

const SUPPORTED_TYPES: u8

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 ToCss for SuperellipseArg

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.

fn to_css_cssstring(&self) -> String

Serialize self in CSS syntax and return a CssString.

impl ToShmem for SuperellipseArg

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

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

impl ToTyped for SuperellipseArg

fn to_typed(&self, dest: &mut ThinVec<TypedValue>) -> Result<(), ()>

Attempt to convert self into one or more TypedValue items.

fn to_typed_value(&self) -> Option<TypedValue>

Attempt to convert self into a TypedValue.

fn to_numeric_value(&self) -> Option<NumericValue>

Attempt to convert self into a NumericValue.

fn to_typed_value_list(&self) -> Option<TypedValueList>

Attempt to convert self into a TypedValueList.
