Implementations

impl NoCalcLength

pub fn to_computed_value_with_base_size( &self, context: &Context<'_>, base_size: FontBaseSize, line_height_base: LineHeightBase, ) -> Length

Computes a length with a given font-relative base size.

impl NoCalcLength

pub fn unitless_value(&self) -> CSSFloat

Return the unitless, raw value.

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

pub fn is_negative(&self) -> bool

Returns whether the value of this length without unit is less than zero.

pub fn is_zero(&self) -> bool

Returns whether the value of this length without unit is equal to zero.

pub fn is_infinite(&self) -> bool

Returns whether the value of this length without unit is infinite.

pub fn is_nan(&self) -> bool

Returns whether the value of this length without unit is NaN.

pub fn should_zoom_text(&self) -> bool

Whether text-only zoom should be applied to this length.

Generally, font-dependent/relative units don’t get text-only-zoomed, because the font they’re relative to should be zoomed already.

pub fn parse_dimension( context: &ParserContext<'_>, value: CSSFloat, unit: &str, ) -> Result<Self, ()>

Parse a given absolute or relative dimension.

pub(crate) fn try_op<O>(&self, other: &Self, op: O) -> Result<Self, ()>

where O: Fn(f32, f32) -> f32,

pub(crate) fn map(&self, op: impl FnMut(f32) -> f32) -> Self

pub fn to_computed_pixel_length_without_context(&self) -> Result<CSSFloat, ()>

Get a px value without context (so only absolute units can be handled).

pub fn from_px(px_value: CSSFloat) -> NoCalcLength

Get an absolute length from a px value.

Trait Implementations

impl Clone for NoCalcLength

fn clone(&self) -> NoCalcLength

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for NoCalcLength

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

Formats the value using the given formatter.

impl From<NoCalcLength> for Length

fn from(len: NoCalcLength) -> Self

Converts to this type from the input type.

impl From<NoCalcLength> for LengthPercentage

fn from(len: NoCalcLength) -> Self

Converts to this type from the input type.

impl From<NoCalcLength> for NonNegativeLength

fn from(len: NoCalcLength) -> Self

Converts to this type from the input type.

impl From<NoCalcLength> for NonNegativeLengthPercentage

fn from(len: NoCalcLength) -> Self

Converts to this type from the input type.

impl MallocSizeOf for NoCalcLength

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 NoCalcLength

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

fn partial_cmp(&self, other: &Self) -> 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 SpecifiedValueInfo for NoCalcLength

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 NoCalcLength

type ComputedValue = CSSPixelLength

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 NoCalcLength

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

where W: Write,
