Struct FontMetrics 

pub struct FontMetrics {
    pub family: String,
    pub style: String,
    pub weight: u16,
    pub units_per_em: Option<u16>,
    pub ascender: Option<i32>,
    pub descender: Option<i32>,
}

Font metrics for exact text reproduction.

Fields

family: String

Font family name.

style: String

Font style (normal, italic).

weight: u16

Font weight (100-900).

units_per_em: Option<u16>

Units per em.

ascender: Option<i32>

Ascender height in font units.

descender: Option<i32>

Descender depth in font units (typically negative).

Implementations

impl FontMetrics

pub fn new(family: impl Into<String>) -> Self

Create font metrics for a font family.

pub fn with_style(self, style: impl Into<String>) -> Self

Set font style.

pub fn with_weight(self, weight: u16) -> Self

Set font weight.

pub fn with_metrics( self, units_per_em: u16, ascender: i32, descender: i32, ) -> Self

Set detailed font metrics.

Trait Implementations

impl Clone for FontMetrics

fn clone(&self) -> FontMetrics

Returns a duplicate 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<'de> Deserialize<'de> for FontMetrics

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

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.

impl Serialize for FontMetrics

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
