Struct FontTable 

pub struct FontTable {
    pub fonts: Vec<FontInfo>,
    pub id_cs: Vec<CsId>,
    pub loader: Option<Box<dyn FontLoader>>,
    pub dense: Vec<DenseMetrics>,
}

The table of loaded fonts.

Fields

fonts: Vec<FontInfo>

Fonts by id; id 0 is \nullfont.

id_cs: Vec<CsId>

Identifier control sequence of each font (TeX’s font_id_text).

loader: Option<Box<dyn FontLoader>>

The loader, if any.

dense: Vec<DenseMetrics>

Dense metric tables for fast lookup of small character codes, by font id (see FontTable::sync_dense).

Implementations

impl FontTable

pub fn sync_dense(&mut self)

Builds the dense tables of fonts added since the last call. Call before hot loops; the character metrics of a font must not change afterwards (call FontTable::invalidate_dense if they do).

pub fn invalidate_dense(&mut self, f: u32)

Forgets the dense table of font f and those after it.

pub fn char_metrics(&self, f: u32, c: u32) -> Option<&CharMetrics>

The metrics of character c in font f.

Trait Implementations

impl Debug for FontTable

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

Formats the value using the given formatter.

impl Default for FontTable

fn default() -> Self

Returns the “default value” for a type.
