Macro cstr

macro_rules! cstr {
    ($s:expr) => { ... };
}

Converts a string slice to &CStr.

The C-style string is guaranteed to be terminated by a nul byte. This trailing nul byte will be appended by this macro. The provided data should not contain any nul bytes in it.

This macro is const-context only.

See also raw_cstr!.

Note that Rust has supported C string literals since 1.77.0.

Examples

use core::ffi::CStr;;
const PRINTF_FMT: &CStr = const_str::cstr!("%d\n");
