-# generic-array
-
-This crate implements generic array types for Rust.
-
-[Documentation](http://fizyk20.github.io/generic-array/generic_array/)
-
-## Usage
-
-The Rust arrays `[T; N]` are problematic in that they can't be used generically with respect to `N`, so for example this won't work:
-
-```rust
-struct Foo<N> {
- data: [i32; N]
-}
-```
-
-**generic-array** defines a new trait `ArrayLength<T>` and a struct `GenericArray<T, N: ArrayLength<T>>`, which let the above be implemented as:
-
-```rust
-struct Foo<N: ArrayLength<i32>> {
- data: GenericArray<i32, N>
-}
-```
-
-To actually define a type implementing `ArrayLength`, you can use unsigned integer types defined in [typenum](https://github.com/paholg/typenum) crate - for example, `GenericArray<T, U5>` would work almost like `[T; 5]` :)
-
-In version 0.1.1 an `arr!` macro was introduced, allowing for creation of arrays as shown below:
-
-```rust
-let array = arr![u32; 1, 2, 3];
-assert_eq!(array[2], 3);
-```
