+
+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 1.46 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());
+```
