Struct FontConf 

pub struct FontConf { /* private fields */ }

generic families, substitutes and language choices (see the module header)

Implementations

impl FontConf

pub fn new() -> FontConf

pub fn system() -> FontConf

the rules of this system (see the module header)

pub fn files(&self) -> usize

fontconfig files read

pub fn load(&mut self, path: &str) -> bool

add the rules of a fontconfig file (and of what it includes) -> it could be read

pub fn parse(&mut self, text: &str, dir: &str) -> usize

add the rules of fontconfig text (includes relative to dir) -> rules found

pub fn add_alias( &mut self, family: &str, prefer: &[&str], accept: &[&str], default: &[&str], )

add an alias: prefer before the family, accept after it, default at the end

pub fn add_lang( &mut self, lang: Option<&str>, family: Option<&str>, mode: u8, families: &[&str], )

add a language rule (lang None: every language; family None: every family)

pub fn candidates(&self, family: &str, lang: &str) -> Vec<String>

the families to try for a name in a language, best first (each once; generic names stay in the list where they stand)

pub fn lang_families(&self, lang: &str) -> Vec<String>

the families a language adds to sans-serif (fallback.rs tries them first)
