Class Method Details

._uniffi_allocate(pointer) ⇒ Object

A private helper for initializing instances of the class from a raw pointer, bypassing any initialization logic and ensuring they are GC’d properly.

end

._uniffi_define_finalizer_by_pointer(pointer, object_id) ⇒ Object

A private helper for registering an object finalizer. N.B. it’s important that this does not capture a reference to the actual instance, only its underlying pointer.

      pointer
    )
  end
end

._uniffi_lower(inst) ⇒ Object

A private helper for lowering instances into a raw pointer. This does an explicit typecheck, because accidentally lowering a different type of object in a place where this type is expected, could lead to memory unsafety.
