Struct FontResolverImpl

pub struct FontResolverImpl { /* private fields */ }

The default FontResolver implementation.

This is constructed by:

• The crate::font::system::SystemFontSearcher on operating systems.
• The crate::font::web::BrowserFontSearcher on browsers.
• Otherwise, crate::font::pure::MemoryFontBuilder in memory.

Implementations

impl FontResolverImpl

pub fn new( font_paths: Vec<PathBuf>, book: FontBook, slots: Vec<FontSlot>, ) -> FontResolverImpl

Creates a new font resolver.

pub fn new_with_fonts( font_paths: Vec<PathBuf>, fonts: impl Iterator<Item = (FontInfo, FontSlot)>, ) -> FontResolverImpl

Creates a new font resolver with fonts.

pub fn len(&self) -> usize

Gets the number of fonts in the resolver.

pub fn is_empty(&self) -> bool

Checks if the resolver holds any fonts.

pub fn font_paths(&self) -> &[PathBuf]

Gets the user-specified font paths.

pub fn get_fonts(&self) -> impl Iterator<Item = (&FontInfo, &FontSlot)>

👎Deprecated: use fonts instead

Returns an iterator over all fonts in the resolver.

pub fn fonts(&self) -> impl Iterator<Item = (&FontInfo, &FontSlot)>

Returns an iterator over all fonts in the resolver.

pub fn loaded_fonts(&self) -> impl Iterator<Item = (usize, Font)>

Returns an iterator over all loaded fonts in the resolver.

pub fn describe_font(&self, font: &Font) -> Option<Arc<DataSource>>

Describes the source of a font.

pub fn describe_font_by_id(&self, index: usize) -> Option<Arc<DataSource>>

Describes the source of a font by index.

pub fn with_font_paths(self, font_paths: Vec<PathBuf>) -> FontResolverImpl

Sets the user-specified font paths.

Trait Implementations

impl Debug for FontResolverImpl

impl FontResolver for FontResolverImpl

fn font_book(&self) -> &LazyHash<FontBook>

The font book interface for typst.

fn slot(&self, idx: usize) -> Option<&FontSlot>

fn font(&self, index: usize) -> Option<Font>

Gets the font by index. The index parameter is the index of the font in the FontBook.infos.

fn get_by_info(&self, info: &FontInfo) -> Option<Font>

Gets a font by its info.

fn revision(&self) -> Option<NonZero<usize>>

An optionally implemented revision function for users, e.g. the World.

fn default_get_by_info(&self, info: &FontInfo) -> Option<Font>

The default implementation of FontResolver::get_by_info.

impl ReusableFontResolver for FontResolverImpl

fn slots(&self) -> impl Iterator<Item = FontSlot>

Returns an iterator over all slots in the resolver.
