Ranges/Aliases

Ranges

A range represents a range of numbers or in some contexts a range of types. A range has a lower and a upper bound.

let range = 1..200;

The sample above uses a range from 1 to 200 inclusive. That means an array will be instantiated with all the values from 1 to 200.

Type Aliases

You can use a type by a custom name. This is called a type alias. (Currently type aliases are bound to the whole assembly/program)

The definition:

<type_alias> ::= "using" <identifier> "as" <identifier> ";"

Example:

using int as i32;

func main() -> int {
  return 42;
}

As you can see in the sample above the alias type can be used as if it were a normal integer.
