c_str! macro for Rust

This macro-only crate provides the c_str! macro to facilitate creation of C-compatible string values from Rust string literals.

Legacy code

This repository also contains source code for crate c_string, which is no longer maintained. It provided some utility types to facilitate working with C-compatible strings in Rust, but most of them were poorly designed or do not fit well with the evolution of the language. The topmost commit for that crate is available under branch c-string.
