Provided methods

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

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

The default implementation, which is used by the DirectWrite and the filesystem backends, does a brute-force search of installed fonts to find the one that matches.

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.
