Array types

ArrayType :

An array is a fixed-size sequence of N elements of type T. The array type is written as Array<T, N>. The size is an integer literal.

Arrays are either stored in storage or memory but are never stored directly on the stack.


contract Foo {
  // An array in storage
  bar: Array<u8, 10>

  fn do_something() {
    // An array in memory
    let values: Array<u256, 3> = [10, 100, 100]

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