Struct font_kit::sources::fontconfig::FontconfigSource
source · [−]pub struct FontconfigSource { /* private fields */ }Expand description
A source that contains the fonts installed on the system, as reported by the Fontconfig library.
On macOS and Windows, the Cargo feature source-fontconfig can be used to opt into fontconfig
support. To prefer it over the native font source (only if you know what you’re doing), use the
source-fontconfig-default feature.
Implementations
sourceimpl FontconfigSource
impl FontconfigSource
sourcepub fn new() -> FontconfigSource
pub fn new() -> FontconfigSource
Initializes Fontconfig and prepares it for queries.
sourcepub fn all_fonts(&self) -> Result<Vec<Handle>, SelectionError>
pub fn all_fonts(&self) -> Result<Vec<Handle>, SelectionError>
Returns paths of all fonts installed on the system.
sourcepub fn all_families(&self) -> Result<Vec<String>, SelectionError>
pub fn all_families(&self) -> Result<Vec<String>, SelectionError>
Returns the names of all families installed on the system.
sourcepub fn select_family_by_name(
&self,
family_name: &str
) -> Result<FamilyHandle, SelectionError>
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.
sourcepub fn select_by_postscript_name(
&self,
postscript_name: &str
) -> Result<Handle, SelectionError>
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.
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.
sourcepub fn select_best_match(
&self,
family_names: &[FamilyName],
properties: &Properties
) -> Result<Handle, SelectionError>
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.
