Metrics for a font

Fields

em_size: f32

Size of an em relative to these metrics

ascender: f32

The ascender size for the font

descender: f32

The descender size for the font

height: f32

The height for the font

line_gap: f32

The line gap for the font

capital_height: Option<f32>

The capital height for the font, if specified

underline_position: Option<FontLinePosition>

Offset from the baseline and suggested thickness for an underline (can be None if the font does not specify)

strikeout_position: Option<FontLinePosition>

Offset from the baseline and suggested thickness for a strikeout effect

Implementations

impl FontMetrics

pub fn with_size(self, em_size: f32) -> FontMetrics

Returns the metrics adjusted to a new em size

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 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.
