r[type.array.intro]
An array is a fixed-size sequence of N elements of type T. The array type
is written as [T; N].
r[type.array.constraint]
The size is a constant expression that evaluates to a usize.
Examples:
// 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]);r[type.array.index] 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.
