[−][src]Crate cstr
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
.
Note that it currently cannot be used to initialize constants due to restriction of Rust.
Example
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());
