DMA-Buf Heap Helper Library

The DMA-Buf Heap interface in Linux is aimed at providing a way for the user-space to allocate memory buffers that can be efficiently shared between multiple devices through the DMA-Buf mechanism. It aims at superseeding the ION Interface previously found in Android.

This library provides a safe abstraction over this interface for Rust.

Hello World

```rust,norun use std::os::unix::io::OwnedFd; use dmaheap::{Heap, HeapKind};

let heap = Heap::new(HeapKind::Cma) .unwrap();

// Buffer will automatically be freed when buffer goes out of scope. let buffer: OwnedFd = heap.allocate(1024).unwrap(); ```
