Struct FontConfig 

pub struct FontConfig { /* private fields */ }

Maps font family names to font file paths.

Font names are stored in lowercase for case-insensitive lookup.

Implementations

impl FontConfig

pub fn new() -> Self

Create an empty FontConfig with no font mappings.

pub fn add_mapping(&mut self, name: &str, path: PathBuf)

Add a font mapping: name (case-insensitive) → path.

pub fn find_font(&self, family: &str) -> Option<&PathBuf>

Look up a font file path by family name (case-insensitive).

Returns None if no mapping exists for family.

pub fn with_system_fonts() -> Self

Build a FontConfig by scanning standard system font directories and registering every TTF/OTF file found there.

Font names are extracted from the font file metadata using ttf-parser. If a file cannot be parsed its name is derived from the file stem instead.

pub fn iter(&self) -> impl Iterator<Item = (&str, &PathBuf)>

Return an iterator over all registered (name, path) pairs.

pub fn len(&self) -> usize

Return the number of registered font mappings.

pub fn is_empty(&self) -> bool

Return true if no font mappings are registered.

Trait Implementations

impl Debug for FontConfig

fn fmt(&self, f: &mut Formatter<'_>) -> Result

impl Default for FontConfig

fn default() -> FontConfig

Returns the “default value” for a type.
