Struct FontContext 

pub struct FontContext {
    pub font_size: Length,
    pub x_height: Length,
}

Context for resolving font-relative units

Contains the current font size and x-height needed to resolve em and ex units to absolute lengths.

Fields

font_size: Length

Current font size

x_height: Length

X-height of the current font (typically ~0.5em)

Implementations

impl FontContext

pub fn new(font_size: Length) -> Self

Create a new font context

The x_height will be calculated as 0.5 times the font_size if not explicitly provided.

pub fn with_x_height(font_size: Length, x_height: Length) -> Self

Create a new font context with explicit x-height

Trait Implementations

impl Clone for FontContext

fn clone(&self) -> FontContext

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FontContext

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

Formats the value using the given formatter.

impl PartialEq for FontContext

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