Rust implementation of C's va_list type

Overview

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

Example

```rust extern crate valist; use valist::VaList;

extern "C" printintsva(count: u32, mut args: VaList) { for i in (0 .. count) { println!("{}: {}", i, args.get::()); } } ```

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
