Access to the system fonts.

Implementations§

source§

impl FontSystem

source

pub fn new() -> FontSystem

Create a new FontSystem, that allows access to any installed system fonts

§Timing

This function takes some time to run. On the release build, it can take up to a second, while debug builds can take up to ten times longer. For this reason, it should only be called once, and the resulting FontSystem should be shared.

source

pub fn new_with_fonts(fonts: impl IntoIterator<Item = Source>) -> FontSystem

Create a new FontSystem with a pre-specified set of fonts.

source

pub fn new_with_locale_and_db(locale: String, db: Database) -> FontSystem

Create a new FontSystem with a pre-specified locale and font database.

source

pub fn locale(&self) -> &str

Get the locale.

source

pub fn db(&self) -> &Database

Get the database.

source

pub fn db_mut(&mut self) -> &mut Database

Get a mutable reference to the database.

source

pub fn into_locale_and_db(self) -> (String, Database)

Consume this FontSystem and return the locale and database.

source

pub fn cache_fonts(&mut self, ids: Vec<ID>)

Concurrently cache fonts by id list

source

pub fn get_font(&mut self, id: ID) -> Option<Arc<Font>>

Get a font by its ID.

source

pub fn is_monospace(&self, id: ID) -> bool

source

pub fn get_monospace_ids_for_scripts( &self, scripts: impl Iterator<Item = [u8; 4]>, ) -> Vec<ID>

source

pub fn get_font_supported_codepoints_in_word( &mut self, id: ID, word: &str, ) -> Option<usize>
