A complete STD demo on ESP32C3

I'm trying lots of Rust demos (including rust-esp32-std-demo, esp32-spooky-maze-game) for ESP32 on my M5GO kit with ili9342c controller and all of them struggle to give fullscreen (320x240) frame-rate > 5.

I used this demo as a guide, it uses esp-idf for rust, and allows you to use std

rust-esp32-std-demo works quite well with WiFi, HTTPS and MQTTS. The only thing I could not make work (but I did not put much effort into it) was using async primitives. That part seems to be experimental, indeed.

FWIW I've very recently gotten https://github.com/ivmarkov/rust-esp32-std-demo (which is a pretty comprehensive demo) running on a TinyPICO (w/ESP32) and am looking forward to building out my own projects next.

I'm using this template project to get started with the esp32, though I've started fresh in a new main function. Every time I build the project -even if I only add a blank line to main - it seems to re-compile bindgen and embuild, and regenerate the bindings for a variety of packages that have C components. I haven't made any changes to these though and the process takes a full 90 seconds. In addition nothing in the bindings that are getting generated shows up in intellisense in vscode. Any help appreciated.

This worked fairly well for me. I assume that's where the book takes you, bit I've missed if you said if you're trying to use std or no_std. https://github.com/ivmarkov/rust-esp32-std-demo
