Struct style::font_metrics::FontMetrics

pub struct FontMetrics {
    pub x_height: Option<Length>,
    pub zero_advance_measure: Option<Length>,
    pub cap_height: Option<Length>,
    pub ic_width: Option<Length>,
    pub ascent: Length,
}

Represents the font metrics that style needs from a font to compute the value of certain CSS units like ex.

Fields

x_height: Option<Length>

The x-height of the font.

zero_advance_measure: Option<Length>

The zero advance. This is usually writing mode dependent

cap_height: Option<Length>

The cap-height of the font.

ic_width: Option<Length>

The ideographic-width of the font.

ascent: Length

The ascent of the font (a value is always available for this).

Trait Implementations

impl Clone for FontMetrics

fn clone(&self) -> FontMetrics

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for FontMetrics

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

Formats the value using the given formatter.

impl Default for FontMetrics

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq<FontMetrics> for FontMetrics

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