Implementations§

source§

impl NoCalcLength

source

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.

source§

impl NoCalcLength

source

pub fn unitless_value(&self) -> CSSFloat

Return the unitless, raw value.

source

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

source

pub fn is_negative(&self) -> bool

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

source

pub fn is_zero(&self) -> bool

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

source

pub fn is_infinite(&self) -> bool

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

source

pub fn is_nan(&self) -> bool

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

source

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.

source

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

Parse a given absolute or relative dimension.

source

pub(crate) fn try_op<O>(&self, other: &Self, op: O) -> Result<Self, ()>
where O: Fn(f32, f32) -> f32,

source

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

source

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

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

source

pub fn from_px(px_value: CSSFloat) -> NoCalcLength

Get an absolute length from a px value.
