Have you wanted to be able to initialize a fixed array in Rust by calling a function to create each
element? Now you can!
```rust
use init_with::InitWith;
let my_array = {
let mut seed = Vec::new();
let mut next_val = 0;
<[Vec<u32>; 3]>::init_with(|| {
seed.push(next_val);
next_val += 1;
seed.clone()
})
};
assert_eq!(my_array, [vec![0], vec![0, 1], vec![0, 1, 2]]);
```
This crate lets you initialize the array elements in a functional manner while hiding the unsafe
code that's needed to do so.
To import this crate, put the following into your Cargo.toml:
```toml
[dependencies]
init_with = "0.1.1"
```
...and the following in your crate root:
```rust
extern crate init_with;
```
