The number of mentions indicates the total number of mentions that we've tracked plus the number of user suggested alternatives.
Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Rust on Espressif chips – 29-09-2023
In the esp-hal, they appear to offer both sync and async I2C implementations, depending on what works best for an application. Since the async implementation is gated by a feature, it may not show up in the docs you linked.
Async implementation: https://github.com/esp-rs/esp-hal/blob/main/esp-hal-common/s...
You can also see the async feature mentioned here: https://docs.rs/crate/esp32s2-hal/latest/features

The Embedded Rust ESP Development Ecosystem
Going another level up the chain, we then have the hardware abstraction layer (HAL) crate. HAL crates are supposed to offer more portability and user-friendly API for a particular processor. For ESP devices the different hals are captured in the esp-hal repository. This occurs by implementing some common traits defined in what is referred to as the embedded-hal. Additionally, the device HAL attempts to incorporate mechanisms, or wrappers around lower-level functions, that are part of the Rust safety model.

How to write HALs and get into microcontroller programming
There is https://docs.rust-embedded.org/book/design-patterns/hal/index.html but I wonder what OP is missing in https://github.com/esp-rs/esp-hal
What are some alternatives?
When comparing no_std-training and esp-hal you can also consider the following projects:
esp32-spooky-maze-game - Rust Bare Metal implementation of maze game for ESP32
esp-idf-hal - embedded-hal implementation for Rust on ESP32 and ESP-IDF
esp-wifi-sys - Wi-Fi and BT drivers packaged for integration into bare-metal esp-wifi.
talc - A fast and flexible allocator for no_std and WebAssembly
esp32-phantom - ESP32 Rust-based WiFi and BLE sandbox
