Struct FontMetrics

#[repr(C)]
pub struct FontMetrics {
    pub ascent: Coord,
    pub descent: Coord,
    pub x_height: Coord,
    pub cap_height: Coord,
}

A structure to hold metrics of a font for a specified pixel size.

Fields

ascent: Coord

The distance between the baseline and the top of the tallest glyph in the font.

descent: Coord

The distance between the baseline and the bottom of the tallest glyph in the font. This is usually negative.

x_height: Coord

The distance between the baseline and the horizontal midpoint of the tallest glyph in the font, or zero if not specified by the font.

cap_height: Coord

The distance between the baseline and the top of a regular upper-case glyph in the font, or zero if not specified by the font.

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() -> FontMetrics

Returns the “default value” for a type.

impl PartialEq for FontMetrics

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