ArrayType :
   [ Type ; Expression ]

An array is a fixed-size sequence of N elements of type T. The array type is written as [T; N]. The size is an expression that evaluates to a usize.

Examples:

# #![allow(unused_variables)]
#fn main() {
// A stack-allocated array
let array: [i32; 3] = [1, 2, 3];

// A heap-allocated array, coerced to a slice
let boxed_array: Box<[i32]> = Box::new([1, 2, 3]);
#}

All elements of arrays are always initialized, and access to an array is always bounds-checked in safe methods and operators.

Note: The Vec<T> standard library type provides a heap-allocated resizable array type.
