# Unarray

Utilities for working with uninitialized arrays

This crate provides a few sets of APIs:

## `uninit_buf` and `mark_initialized`

These are a pair of functions which are generally used as follows:
 - stack-allocate an uninitialized array with `uninit_buf`
 - initialize each element
 - unsafely convert it to an initialized array with `mark_initialized`

For example:
```rust
use unarray::*;

fn main() {
  let mut buffer = uninit_buf::<i32; 10>();

  for slot in &mut buffer {
    slot.write(123);
  }

  let array = unsafe { mark_initialized(buffer) };

  assert_eq!(array, [123; 10]);
}
```

This is simple to understand, but still requires `unsafe`, which is hard to justify in many cases
