# no_std libc print/println/eprint/eprintln/dbg
[](https://travis-ci.org/mmastrac/rust-libc-print)
[](https://docs.rs/libc-print)
[](https://crates.io/crates/libc-print)
Implements `println!`, `eprintln!` and `dbg!` on 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).
By default this crate provides `libc_`-prefixed macros, but also allows consumers to
import macros with the same name as the stdlib printing macros via the `std_name`
module.
## Usage
Exactly as you'd use `println!`, `eprintln!` and `dbg!`.
```rust
#![no_std]
// 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:
```rust
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);
```
