Enum parcel_css::values::length::Length

pub enum Length {
    Value(LengthValue),
    Calc(Box<Calc<Length>>),
}

A CSS <length> value, with support for calc().

Variants

Value(LengthValue)

An explicitly specified length value.

Calc(Box<Calc<Length>>)

A computed length value using calc().

Implementations

impl Length

pub fn px(px: CSSNumber) -> Length

Constructs a length with the given pixel value.

pub fn to_px(&self) -> Option<CSSNumber>

Attempts to convert the length to pixels. Returns None if the conversion is not possible.

Trait Implementations

impl Add<Length> for Length

type Output = Length

The resulting type after applying the + operator.

fn add(self, other: Length) -> Length

Performs the + operation.

impl Clone for Length

fn clone(&self) -> Length

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Length

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

Formats the value using the given formatter.

impl From<Calc<Length>> for Length

fn from(calc: Calc<Length>) -> Length

Converts to this type from the input type.

impl Into<Calc<Length>> for Length

fn into(self) -> Calc<Length>

Converts this type into the (usually inferred) input type.

impl Mul<f32> for Length

type Output = Length

The resulting type after applying the * operator.

fn mul(self, other: CSSNumber) -> Length

Performs the * operation.

impl<'i> Parse<'i> for Length

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

Parse a value of this type using an existing parser.

fn parse_string(input: &'i str) -> Result<Self, ParseError<'i, ParserError<'i>>>

Parse a value from a string.

impl PartialEq<Length> for Length

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

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

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

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

impl PartialOrd<Length> for Length

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

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

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

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

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

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

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

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

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

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

impl ToCss for Length

fn to_css<W>(
    &self,
    dest: &mut Printer<'_, '_, '_, W>
) -> Result<(), PrinterError> where
    W: Write, 

Serialize self in CSS syntax, writing to dest.

fn to_css_string(
    &self,
    options: PrinterOptions<'_>
) -> Result<String, PrinterError>

Serialize self in CSS syntax and return a string.

impl TryFrom<Angle> for Length

type Error = ()

The type returned in the event of a conversion error.

fn try_from(_: Angle) -> Result<Self, Self::Error>

Performs the conversion.

impl TryMap for Length

fn try_map<F: FnOnce(f32) -> f32>(&self, op: F) -> Option<Self>

Returns the result of the operation, if possible.

impl TryOp for Length

fn try_op<F: FnOnce(f32, f32) -> f32>(&self, rhs: &Self, op: F) -> Option<Self>

Returns the result of the operation in the same type, if possible.

fn try_op_to<T, F: FnOnce(f32, f32) -> T>(&self, rhs: &Self, op: F) -> Option<T>

Returns the result of the operation in a different type, if possible.

impl TrySign for Length

fn try_sign(&self) -> Option<f32>

Returns the sign of the value, if possible.

fn is_sign_positive(&self) -> bool

Returns whether the value is positive. If not possible, returns false.

fn is_sign_negative(&self) -> bool

Returns whether the value is negative. If not possible, returns false.

impl Zero for Length

fn zero() -> Length

Returns the zero value.

fn is_zero(&self) -> bool

Returns whether the value is zero.
