[![Build Status](https://travis-ci.org/Amanieu/cstr_core.svg?branch=master)](https://travis-ci.org/Amanieu/cstr_core) [![Crates.io](https://img.shields.io/crates/v/cstr_core.svg)](https://crates.io/crates/cstr_core)

This crate provides implementations of `CStr` and `CString` which do not depend on the standard library and are suitable for `no_std` environments.

`CString` support is only available if the `alloc` feature is enabled, which requires the `alloc` crate.
`CStr` is always available.

Some hardware targets (e.g. thumbv6m-none-eabi for Cortex M0,M0+) have no support for atomic operations. For these platforms, disable the `arc` feature to omit the parts of the crate that depend on atomic operations. Compatibility with thead-safe code and `Arc<T>` will not be available. 

In addition, the `nightly` feature allows the usage of `CStr::from_bytes_with_nul_unchecked` to be used in a `const` context. However, it requires a nightly version of the compiler.
