Crate libc_print
source · [−]Expand description
Implements println!, eprintln! and dbg! on top of the libc crate without requiring
the use of an allocator.
Allows you to use these macros in a #![no_std] context, or in a situation where the traditional Rust streams might not be available (ie: at process shutdown time).
libc_writeln and libc_ewriteln are provided for cases where you may not wish
to pull in the overhead of the formatter code and simply wish to print C-style strings.
Usage
Exactly as you’d use println!, eprintln! and dbg!.
// Use the default `libc_`-prefixed macros:
libc_println!("Hello {}!", "stdout");
libc_eprintln!("Hello {}!", "stderr");
let a = 2;
let b = libc_dbg!(a * 2) + 1;
assert_eq!(b, 5);Or you can import aliases to std names:
use libc_print::std_name::{println, eprintln, dbg};
println!("Hello {}!", "stdout");
eprintln!("Hello {}!", "stderr");
let a = 2;
let b = dbg!(a * 2) + 1;
assert_eq!(b, 5);Modules
This package contains the libc_print macros, but using the stdlib names
such as println!, print!, etc.
