Struct MappingIndex

Source 
pub struct MappingIndex { /* private fields */ }
Expand description

Cacheable indices of selected mapping tables for materializing a character map.

Since Charmap carries a lifetime, it is difficult to store in a cache. This type serves as an acceleration structure that allows for construction of a character map while skipping the search for the most suitable Unicode mappings.

Implementations§

Source§

impl MappingIndex

Source

pub fn new(font: &FontRef<'_>) -> MappingIndex

Finds the indices of the most suitable Unicode mapping tables in the given font.

Source

pub fn charmap<'a>(&self, font: &FontRef<'a>) -> Charmap<'a>

Creates a new character map for the given font using the tables referenced by the precomputed indices.

The font should be the same as the one used to construct this object.
