Rust implementation of C's va_list type

Overview

This crate provides a rust VaListtype, which is binary-compatible for the C va_list type. It is intended to allow rust code to provide the complex logic of variable argument functions.

Example

extern crate va_list;
use va_list::VaList;

extern "C" print_ints_va(count: u32, mut args: VaList)
{
	for i in (0 .. count) {
		println!("{}: {}", i, args.get::<i32>());
	}
}

Status

  • x86-64 linux/ELF ABI (aka System-V) : Tested in the wild, works relatively well
  • x86 linux/ELF ABI (sys-v) : Unit tested only
