//! # GPIO support module.
//!
//! Contains abstractions to use the pins provided by the [crate::pins] module as GPIO or
//! IO peripheral pins.
//!
//! The core data structures provided for this are the
//!
//! - [Output] for push-pull output pins.
//! - [Input] for input pins.
//! - [Flex] for pins with flexible configuration requirements.
//! - [IoPeriphPin] for IO peripheral pins.
//!
//! The [crate::pins] module exposes singletons to access the [Pin]s required by this module
//! in a type-safe way.
//!
//! # Examples
//!
//! - [Blinky example](https://egit.irs.uni-stuttgart.de/rust/vorago-rs/src/branch/main/va416xx/examples/simple/examples/blinky.rs)
//! - [Async GPIO example](https://egit.irs.uni-stuttgart.de/rust/vorago-rs/src/branch/main/va416xx/examples/embassy/src/bin/async-gpio.rs)
