Trait GlyphLoader 

pub trait GlyphLoader {
    // Required methods
    fn contains_glyph(&mut self, codepoint: char) -> bool;
    fn load_glyph(&mut self, arg: GlyphLoaderArg<'_>);

    // Provided methods
    fn font_baked_init(&mut self, _baked: &mut FontBaked) { ... }
    fn font_baked_destroy(&mut self, _baked: &mut FontBaked) { ... }
}

Trait that implements a custom font loader.

Required Methods

fn contains_glyph(&mut self, codepoint: char) -> bool

Return true if this font loader contains this character.

fn load_glyph(&mut self, arg: GlyphLoaderArg<'_>)

Try to load a glyph.

Refer to GlyphLoaderArg for details.

Provided Methods

fn font_baked_init(&mut self, _baked: &mut FontBaked)

Initialize the parameters of the corresponding FontBaked.

Not needed if this custom loader is part of a font collection and is not the first one.

fn font_baked_destroy(&mut self, _baked: &mut FontBaked)

The font baked is about to be destroyed.

Rarely useful, maybe if you had some raw resource stored in the baked.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
