source 
pub struct Charmap<'a> { /* private fields */ }
Expand description

Maps characters to nominal glyph identifiers.

Implementations§

source§

impl<'a> Charmap<'a>

source

pub fn from_font(font: &FontRef<'a>) -> Self

Creates a character map from the specified font.

source

pub fn proxy(&self) -> CharmapProxy
