//! `no_std` HAL implementations for the peripherals which are common among
//! Espressif devices. Implements a number of the traits defined by
//! [embedded-hal].
//!
//! This crate should not be used directly; you should use one of the
//! device-specific HAL crates instead:
//!
//! - [esp32-hal]
//! - [esp32c3-hal]
//! - [esp32s2-hal]
//! - [esp32s3-hal]
