Enum 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: f32) -> Length

Constructs a length with the given pixel value.

pub fn to_px(&self) -> Option<f32>

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

Trait Implementations

impl Add 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 duplicate 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<(), Error>

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<'any> IntoOwned<'any> for Length

type Owned = Length

A variant of Self with a new lifetime.

fn into_owned(self) -> Length

Make lifetime of self 'static.

impl IsCompatible for Length

fn is_compatible(&self, browsers: Browsers) -> bool

Returns whether the value is compatible with all of the given browser targets.

impl Mul<f32> for Length

type Output = Length

The resulting type after applying the * operator.

fn mul(self, other: f32) -> Length

Performs the * operation.

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

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

impl PartialEq for Length

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

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

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.

fn to_css<W>( &self, dest: &mut Printer<'_, '_, '_, W>, ) -> Result<(), Error<PrinterErrorKind>>

where W: Write,

Serialize self in CSS syntax, writing to dest.

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

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<Length, <Length as TryFrom<Angle>>::Error>

Performs the conversion.

impl TryInto<Angle> for Length

type Error = ()

The type returned in the event of a conversion error.

fn try_into(self) -> Result<Angle, <Length as TryInto<Angle>>::Error>

Performs the conversion.

impl TryMap for Length

fn try_map<F>(&self, op: F) -> Option<Length>

where F: FnOnce(f32, f32) -> f32,

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

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

where F: FnOnce(f32, f32) -> 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.
