//! A helper crate to abstract away the state management and string parsing of
//! AT command communication.
//!
//! It works by creating structs for each AT command, that each implements
//! [`AtatCmd`]. With corresponding response structs that each implements
//! [`AtatResp`].
//!
//! This can be simplified alot using the [`atat_derive`] crate!
//!
//! [`AtatCmd`]: trait.AtatCmd.html
//! [`AtatResp`]: trait.AtatResp.html
//! [`atat_derive`]: <https://crates.io/crates/atat_derive>
//!
//! # Examples
//!
//! ### Command and response example without `atat_derive`:
//! ```
//! use atat::{AtatCmd, AtatResp, Error, InternalError};
//! use core::fmt::Write;
//! use heapless::{String, Vec};
//!
//! pub struct SetGreetingText<'a> {
//! pub text: &'a str,
//! }
//!
//! pub struct GetGreetingText;
//!
//! pub struct NoResponse;
//!
//! impl AtatResp for NoResponse {};
//!
//! pub struct GreetingText {
//! pub text: String<64>,
//! };
//!
//! impl AtatResp for GreetingText {};
//!
//! impl<'a> AtatCmd for SetGreetingText<'a> {
//! type Response = NoResponse;
//! const MAX_LEN: usize = 64;
//!
//! fn write(&self, mut buf: &mut [u8]) -> usize {
//! let buf_len = buf.len();
//! use embedded_io::Write;
//! write!(buf, "AT+CSGT={}", self.text);
//! buf_len - buf.len()
//! }
//!
//! fn parse(&self, resp: Result<&[u8], InternalError>) -> Result<Self::Response, Error> {
//! Ok(NoResponse)
//! }
//! }
//!
//! impl AtatCmd for GetGreetingText {
//! type Response = GreetingText;
//! const MAX_LEN: usize = 8;
//!
//! fn write(&self, mut buf: &mut [u8]) -> usize {
//! let cmd = b"AT+CSGT?";
//! let len = cmd.len();
//! buf[..len].copy_from_slice(cmd);
//! len
//! }
//!
//! fn parse(&self, resp: Result<&[u8], InternalError>) -> Result<Self::Response, Error> {
//! // Parse resp into `GreetingText`
//! Ok(GreetingText {
//! text: String::try_from(core::str::from_utf8(resp.unwrap()).unwrap()).unwrap(),
//! })
//! }
//! }
//! ```
//!
//! ### Same example with `atat_derive`:
//! ```
//! use atat::atat_derive::{AtatCmd, AtatResp};
//! use heapless::String;
//!
//! #[derive(Clone, AtatCmd)]
//! #[at_cmd("+CSGT", NoResponse)]
//! pub struct SetGreetingText<'a> {
//! #[at_arg(position = 0, len = 32)]
//! pub text: &'a str,
//! }
//!
//! #[derive(Clone, AtatCmd)]
//! #[at_cmd("+CSGT?", GreetingText)]
//! pub struct GetGreetingText;
//!
//! #[derive(Clone, AtatResp)]
//! pub struct NoResponse;
//!
//! #[derive(Clone, AtatResp)]
//! pub struct GreetingText {
//! #[at_arg(position = 0)]
//! pub text: String<64>,
//! };
//! ```
//!
//! ### Basic usage example (More available in examples folder):
