no_std libc print/println/eprint/eprintln
Implements println!
and eprintln!
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!
or eprintln!
.
#![no_std]
// ...
libc_println!("Hello {}!", "world");
