• Supports almost all ESP IDF services: timers, event loop, Wifi, Ethernet, HTTP client & server, MQTT, WS, NVS, OTA, etc.
• Implements the traits of embedded-svc
• Blocking and async mode for each service (async support where feasible)
• Re-exports esp-idf-hal and esp-idf-sys as esp_idf_svc::hal and esp_idf_svc::sys. You only need to depend on esp_idf_svc to get everything you need

You might want to also check out the ESP IDF Drivers wrappers, and the raw bindings to ESP IDF in the esp-idf-sys crate!

Please note that all esp-idf-* crates are a community effort, in that Espressif puts little to no paid developer time in these. So while ESP-IDF itself is very popular and well tested, the esp-idf-* crates:

• Might be a bit lagging behind the latest stable ESP-IDF version
• Are (currently) missing HIL tests
• Need more documentation

For a HAL which is officially supported by Espressif (as in - with paid developer time), please look at esp-hal. Keep in mind that esp-hal is no_std-only, does not use ESP-IDF and requires async programming.

Follow the Prerequisites section in the esp-idf-template crate.

The examples could be built and flashed conveniently with cargo-espflash. To run e.g. wifi on an e.g. ESP32-C3: (Swap the Rust target and example name with the target corresponding for your ESP32 MCU and with the example you would like to build)

with cargo-espflash:

$ MCU=esp32c3 cargo espflash flash --target riscv32imc-esp-espidf --example wifi --monitor

Use the esp-idf-template project. Everything would be arranged and built for you automatically - no need to manually clone the ESP IDF repository.
