Type Aliases

Type aliases are equivalent to C's typedef:

typealias size_t = Int32;

Enums are similar to C++ but always scoped:

enum Color {
    Red, Green = 2, Blue
}

fun foo(c: Color) {}

foo(Color::Red);

Explicit size specification:

enum Color : UInt8 {
    Red, Green = 2, Blue
}

Unsafe structs match their C++ counterparts exactly, without safety check markers. Extern structs are unsafe by default.

Within unsafe structs, this is a raw pointer (not safe pointer). Objects allocated with new can be converted to safe pointers using rawToRef:

unsafe struct A {
    fun foo() {
        var self = rawToRef(this);
    }
}
