Struct font_kit::sources::core_text::CoreTextSource

pub struct CoreTextSource;

A source that contains the installed fonts on macOS.

Implementations

impl CoreTextSource

pub fn new() -> CoreTextSource

Opens a new connection to the system font source.

(Note that this doesn’t actually do any Mach communication to the font server; that is done lazily on demand by the Core Text/Core Graphics API.)

pub fn all_fonts(&self) -> Result<Vec<Handle>, SelectionError>

Returns paths of all fonts installed on the system.

pub fn all_families(&self) -> Result<Vec<String>, SelectionError>

Returns the names of all families installed on the system.

pub fn select_family_by_name(
    &self,
    family_name: &str
) -> Result<FamilyHandle, SelectionError>

Looks up a font family by name and returns the handles of all the fonts in that family.

pub fn select_by_postscript_name(
    &self,
    postscript_name: &str
) -> Result<Handle, SelectionError>

Selects a font by PostScript name, which should be a unique identifier.

pub fn select_best_match(
    &self,
    family_names: &[FamilyName],
    properties: &Properties
) -> Result<Handle, SelectionError>

Performs font matching according to the CSS Fonts Level 3 specification and returns the handle.
