There are alternatives to rusttype such as ab_glyph and fontdue and msdfgen. Compare them to each-other to see which one might be best to use for immediate mode.

Another possibility is to use glyph-brush, or part of it, to integrate font-atlas functionality.

glyph_brush_draw_cache Seems to be a promising replacement for my currently lackluster font atlas, and has features I was hoping to support, like queuing glyphs to be rasterized later in frame. I may also consider adopting glyph_brush_layout in the future to support better text layout.

Update:
Upon further investigation, glyphs that are cached cannot be allocated in the texture separately from being rasterized; they are queued for rasterization when they are looked up and not found in the cache. I was hoping for behavior where the glyphs are allocated into the texture upon lookup if it isn't cached, and then rasterization happens at the end of frame.

I have settled on:

fontdb to store font data and support multiple fonts
ttf_parser for font parsing
msdfgen_rs for rasterizing
guillotiere to implement texture packing in the glyph texture atlas

It could be fun to add rich-text like functionality through ANSI escape codes
