Pointer[A: A]

[Source]

A Pointer[A] is a raw memory pointer. It has no descriptor and thus can't be included in a union or intersection, or be a subtype of any interface. Most functions on a Pointer[A] are private to maintain memory safety.

struct ref Pointer[A: A]

Constructors

create

[Source]

new ref create()
: Pointer[A] ref^

Returns

• Pointer[A] ref^
