Array types
Syntax
ArrayType :
Array<Type, INTEGER_LITERAL>
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.
Examples:
contract Foo:
# An array in storage
bar: Array<u8, 10>
fn do_something():
# An array in memory
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.
