Enum CssLength 

pub enum CssLength {
    Px(f64),
    Em(f64),
    Rem(f64),
    Vw(f64),
    Vh(f64),
    Percent(f64),
}

CSS length unit with numeric value.

Represents the subset of CSS <length> and <percentage> values relevant to WCAG spatial constraints.

Variants

Px(f64)

Absolute pixels.

Em(f64)

Relative to font size.

Rem(f64)

Relative to root font size.

Vw(f64)

Percentage of viewport width.

Vh(f64)

Percentage of viewport height.

Percent(f64)

Percentage of containing block.

Implementations

impl CssLength

pub fn to_px( &self, font_size_px: f64, root_font_size_px: f64, viewport_width: f64, viewport_height: f64, containing_block: f64, ) -> f64

Resolve to absolute pixels given a context.

• font_size_px: current element’s computed font size
• root_font_size_px: root element’s font size (default 16)
• viewport_width: viewport width in px
• viewport_height: viewport height in px
• containing_block: containing block dimension in px (for %)

Trait Implementations

impl Clone for CssLength

fn clone(&self) -> CssLength

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for CssLength

impl Debug for CssLength

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for CssLength

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for CssLength

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

Formats the value using the given formatter.

impl PartialEq for CssLength

fn eq(&self, other: &CssLength) -> 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.

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
