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>, ) -> Self

Creates a new font resolver.

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

pub fn len(&self) -> usize

Gets the number of fonts in the resolver.

pub fn is_empty(&self) -> bool

Tests whether the resolver doesn’t hold 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, id: usize) -> Option<Arc<DataSource>>

Describes the source of a font by id.

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

impl ReusableFontResolver for FontResolverImpl

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

Reuses the font resolver.
