# cstr

<!-- cargo-sync-readme start -->
A macro for getting `&'static CStr` from literal or identifier.
This macro checks whether the given literal is valid for `CStr`
at compile time, and returns a static reference of `CStr`.
This macro can be used to to initialize constants on Rust 1.64 and above.
## Example
```rust
use cstr::cstr;
use std::ffi::CStr;
let test = cstr!(b"hello\xff");
assert_eq!(test, CStr::from_bytes_with_nul(b"hello\xff\0").unwrap());
let test = cstr!("hello");
assert_eq!(test, CStr::from_bytes_with_nul(b"hello\0").unwrap());
let test = cstr!(hello);
assert_eq!(test, CStr::from_bytes_with_nul(b"hello\0").unwrap());
```
