// Dual logging system compatibility: defmt doesn't support modern format syntax
#![allow(clippy::uninlined_format_args)]

//! ATWINC1500 Wifi module library
//!
//! NOTE: This very much Work In Progress
//!
//! The main entry point is [WincClient].
//!
//! The following traits are implemented:
//!
//! - [embedded_nal::TcpClientStack] and [embedded_nal::TcpFullStack]
//! - [embedded_nal::UdpClientStack] and [embedded_nal::UdpFullStack]
//! - [embedded_nal::Dns]
//!
//! [Examples are available](https://github.com/kaidokert/winc-rs/tree/main/feather/examples)
//! for [Adafruit Feather M0 WiFi](https://www.adafruit.com/product/3010) board.
//!
//! The low-lever library is in the internal `manager` module, it's the part that
//! wraps the HIF protocol and the chip registers.
//!
//! Connecting to AP, getting an IP, DNS lookups etc are implemented.
//!
//! Basic usage:
//! ```no_run
//! # use wincwifi::{WincClient, WifiChannel, Ssid, Credentials, WpaKey};
//! # use embedded_nal::{nb, AddrType, Dns};
//! # fn del_fn(ms: u32) {}
//! # let mut buffer = [0; 1];
//! # let mut spi = buffer.as_mut_slice();
//! // spi: something that implements the protocol transfer
//! let mut client = WincClient::new(spi);
//! let ssid = Ssid::from("ssid").unwrap();
//! let key = Credentials::from_wpa("password").unwrap();
//! nb::block!(client.start_wifi_module());
//! nb::block!(client.connect_to_ap(&ssid, &key, WifiChannel::ChannelAll, false));
//! nb::block!(client.get_host_by_name("google.com", AddrType::IPv4));
//! loop {
//!     client.heartbeat(); // periodically poll the chip
//! }
//! ```
//!
//! Code reference for this implementation is the [Arduino/Atmel Wifi101 library](https://docs.arduino.cc/libraries/wifi101)
//!
