FontSystem

cosmic::iced::daemon::program::graphics::text

Struct FontSystem 

pub struct FontSystem { /* private fields */ }
Expand description

A set of system fonts.

Implementations§

§

impl FontSystem

pub fn raw(&mut self) -> &mut FontSystem

Returns the raw cosmic_text::FontSystem.

pub fn db(&self) -> &Database

Returns a reference to the underlying [fontdb::Database].

Unlike going through raw and db_mut, this does not clear cosmic-text’s internal font-match cache.

pub fn load_font(&mut self, bytes: Cow<'static, [u8]>)

Loads a font from its bytes.

pub fn version(&self) -> Version

Returns the current Version of the FontSystem.

Loading a font will increase the version of a FontSystem.
