Struct TextMetrics 

pub struct TextMetrics {
    pub ascent: f32,
    pub descent: f32,
    pub line_height: f32,
    pub baseline_offset: f32,
}

Font metrics for text layout and positioning.

These metrics describe the vertical characteristics of a font at a given size, useful for precise text layout and baseline alignment.

Fields

ascent: f32

The ascent: distance from baseline to the top of the tallest glyph.

descent: f32

The descent: distance from baseline to the bottom of the lowest glyph (positive value).

line_height: f32

The line height: total vertical space for a line of text.

baseline_offset: f32

The baseline offset from the top of the bounding box. This is typically equal to ascent for top-left positioned text.

Trait Implementations

impl Clone for TextMetrics

fn clone(&self) -> TextMetrics

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TextMetrics

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

Formats the value using the given formatter.

impl PartialEq for TextMetrics

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