Aliasing ​

Type aliases is an alias for existing types defined by developer. When these aliases are used, they qualify the types they represent.

For example:

type int32: i32

fn main() {
    let my_int: int32 = 100
    outln(my_int)
}

As seen in the example above, there is an alias definition of int32 for the i32 data type. The keyword type comes first to define an alias. Then comes the name you want to give and which type it will represent. This alias will now represent i32 when used.

In addition, it seems that this alias is used in variable definition. This is because the compiler recognizes the default types builtin. If your type alias represents a builtin definition, your type alias will not be detected as a type. For this reason, it is a more useful approach to specify specifically.

When defining a type alias, only the following types can be given as the type to represent:

• Builtin Data Types
• Type Aliases
