//! Low level access to Cortex-M processors
//!
//! This crate provides:
//!
//! - Access to core peripherals like NVIC, SCB and SysTick.
//! - Access to core registers like CONTROL, MSP and PSR.
//! - Interrupt manipulation mechanisms
//! - Safe wrappers around Cortex-M specific instructions like `bkpt`
//!
//! # Optional features
//!
//! ## `cm7-r0p1`
//!
//! This feature enables workarounds for errata found on Cortex-M7 chips with revision r0p1. Some
//! functions in this crate only work correctly on those chips if this Cargo feature is enabled
//! (the functions are documented accordingly).
//!
//! # Minimum Supported Rust Version (MSRV)
//!
//! This crate is guaranteed to compile on stable Rust 1.59 and up. It *might*
//! compile with older versions but that may change in any new patch release.
#![deny(missing_docs)]
#![no_std]
#![allow(clippy::identity_op)]
#![allow(clippy::missing_safety_doc)]
// Prevent clippy from complaining about empty match expression that are used for cfg gating.
#![allow(clippy::match_single_binding)]
// This makes clippy warn about public functions which are not #[inline].
//
// Almost all functions in this crate result in trivial or even no assembly.
// These functions should be #[inline].
//
// If you do add a function that's not supposed to be #[inline], you can add
// #[allow(clippy::missing_inline_in_public_items)] in front of it to add an
// exception to clippy's rules.
//
// This should be done in case of:
// - A function containing non-trivial logic (such as itm::write_all); or
// - A generated #[derive(Debug)] function (in which case the attribute needs
// to be applied to the struct).
#![deny(clippy::missing_inline_in_public_items)]
// Don't warn about feature(asm) being stable on Rust >= 1.59.0
