Struct FontSelector 

pub struct FontSelector {
    pub family: FamilySelector,
    pub weight: FontWeight,
    pub width: FontWidth,
    pub style: FontStyle,
}

A font face selection tool

This tool selects a font according to the given criteria from available system fonts. Selection criteria are based on CSS.

This can be converted from a FamilySelector, selecting the default styles.

Fields

family: FamilySelector

Family selector

weight: FontWeight

Weight

width: FontWidth

Width

style: FontStyle

Italic / oblique style

Implementations

impl FontSelector

pub const EMOJI: Self

Hard-coded emoji font selector

pub fn new() -> Self

Synonym for default

Without further parametrization, this will select a generic sans-serif font which should be suitable for most uses.

pub fn format_css(&self) -> Option<String>

Format CSS-style

This is similar to the CSS font property, though it does not support size or variant or using relative or global values. Examples:

• system-ui
• italic bold expanded sans-serif
• oblique 10deg 500 175% monospace
• 300 cursive

Weight, width and style will be omitted if normal. Family is required and must be a single generic name.

Will return None if Self::family is not one of the generic families supported by FamilySelector.

pub fn parse_css(s: &str) -> Option<Self>

Parse a CSS-style selector

Format support is similar to Self::format_css.

Does not (yet) support non-generic font families. TODO: write a nicer parser with real error detection!

Trait Implementations

impl Clone for FontSelector

fn clone(&self) -> FontSelector

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FontSelector

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

Formats the value using the given formatter.

impl Default for FontSelector

fn default() -> FontSelector

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for FontSelector

fn deserialize<D: Deserializer<'de>>(de: D) -> Result<FontSelector, D::Error>

Deserialize this value from the given Serde deserializer.

impl From<FamilySelector> for FontSelector

fn from(family: FamilySelector) -> Self

Converts to this type from the input type.

impl Hash for FontSelector

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for FontSelector

fn eq(&self, other: &FontSelector) -> 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 FontSelector

fn serialize<S: Serializer>(&self, ser: S) -> Result<S::Ok, S::Error>

Serialize this value into the given Serde serializer.

impl Copy for FontSelector

impl Eq for FontSelector

impl StructuralPartialEq for FontSelector
