Expand description
A database of installed fonts that can be queried.
This trait is object-safe.
Required methods
Returns paths of all fonts installed on the system.
fn all_families(&self) -> Result<Vec<String>, SelectionError>
[src]
fn all_families(&self) -> Result<Vec<String>, SelectionError>
[src]Returns the names of all families installed on the system.
fn select_family_by_name(
&self,
family_name: &str
) -> Result<FamilyHandle, SelectionError>
[src]
fn select_family_by_name(
&self,
family_name: &str
) -> Result<FamilyHandle, SelectionError>
[src]Looks up a font family by name and returns the handles of all the fonts in that family.
Accesses this Source
as Any
, which allows downcasting back to a concrete type from a
trait object.
fn as_mut_any(&mut self) -> &mut dyn Any
[src]
fn as_mut_any(&mut self) -> &mut dyn Any
[src]Accesses this Source
as Any
, which allows downcasting back to a concrete type from a
trait object.
Provided methods
fn select_by_postscript_name(
&self,
postscript_name: &str
) -> Result<Handle, SelectionError>
[src]
fn select_by_postscript_name(
&self,
postscript_name: &str
) -> Result<Handle, SelectionError>
[src]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>
[src]
fn select_best_match(
&self,
family_names: &[FamilyName],
properties: &Properties
) -> Result<Handle, SelectionError>
[src]Performs font matching according to the CSS Fonts Level 3 specification and returns the handle.
