Load fonts dynamically

[Erxl]

I'm looking for a way to load fonts dynamically, but I don't know how to implement it

egui::FontDefinitions let's you specify your own TTF data and give to Egui. Use Context::set_fonts to set the new fonts.

Please tell me a bit more about your use case! Is your goal to load fonts for egui_web via a fetch?

EDIT: I simplified how to specify your own fonts in b7d1584

pub type FontData = std::borrow::Cow<'static, [u8]>;

@emilk

if FontData is 'static, can I load font data from the operating system runtime?

[emilk]

Yes, with std::borrow::Cow::Owned

Thanks, I should go learn Cow first.
